Hi everyone,

**I have decided to try reintroducing an information thread. We will see how it goes.**

I want it to be a hub from which interest and discussion threads can be accessed.

I think this is a way of helping to uniting the forum into a little community.

My last wrap, was not not formal and it was not used for long.

My earlier ones give a better idea of what i really wanted but the forum is too big to do it the same now.

ADDRESS OF ORIGINAL WRAP!

http://web2.0calc.com/questions/all-questions-answered-to-this-point

KEY DATES :

This forum was founded by Andre Massow on 25 January 2012. Thanks Mr Massow

I discovered it and joined on 28th September 2013.

My first wrap was the 9th January 2014 and I have posted a wrap almost every day until August 2015

A really major restructure of the forum 13th April 2014,

I was given moderator privileges for the first time on 15th April 2014

(What a great birthday present - just one day early )

http://web2.0calc.com/questions/all-questions-answered-to-this-point#r98

CPhill joined 13th March 2014 and became moderator on 11th May 2014.

Alan joined 24th Feb 2014 and became moderator on the 4th May 2015

A second major restructure of the forum. Sun 30th August 2015

I was away traveling for all of September so although made a new wrap it was never used properly.

And that brings us here, to our 4th Forum Wrap.

-------------------------------------------------------------------------------

Now I would like to bring your attention to a post by Rom. Thank you for posting this Rom

Rom is concerned that answerers are answering but they are all too often NOT facilitating learning.

I intend to write a fuller response on Rom's thread, which is where all this discusion really belongs but I will say here, as I have said many times before that I believe that sometimes/often it is not helpful to give answers alone or to give fully worked answers. And, it is definitely not helpful to answer a string of questions that are all of the same type.

Please try to work with the questioners. Give them hints or suggestions. Some of the very best answers are ones that refer the question asker to other resource sites like "mathsisfun", "purplemaths", or you tube clips. These can often explain much better than we can!

Try and encourage the askers to interact with you. If they won't responding to you it would almost always mean that they are not that interested. You are best to leave it and move to the next question.

PLEASE if an answerer is trying to work with a question asker, for example, they may be requesting input from the asker, please consider hard before you give a full answer of your own. This would undermine your fellow answerer and I think that it is important that answerers are seen to support one another.

I have more to say but it will be said on Rom's thread.

PLEASE RESPOND TO ROM. We need to know what your attitude is. Answerers need to understand each other so that we can work together with more efficiencey and harmony. :)

If you want to comment on teaching verses answering, please do so on Rom's thread. If you want to comment on other matters please do so on the Lantern Thread.

There has been one would be new member "juriemagic" tell me that he cannot log on. I have told him to identify himself at the beginning of the post and I will endeavour to prioritize him as I would any other member.

I wonder how many other people are having this problem. ://

Hi Melody

In response to your query ' I wonder how many other people are having this problem '.

It's been a problem for me ever since the restructuring at the end of August, and it's why you rarely see me logged in these days. I get a message saying that I need to enable cookies, I do that but it has no effect. I notified someone at 2.0calc.com at the time (and received a response), but the problem has not been resolved.

I am able to login using my tablet, but I hate the touch screen, particularly when trying to type in stuff using LaTex, so I rarely use it, for maths that is.

The problem might be caused by the security software that's on my PC, I've messed around with that, but without success.

It would be good if we could get this sorted.

Best wishes

Bertie.

PS. Hope you enjoyed your trip to England.

Thanks Bertie,

I was wondering why you had become so scarce.

I wonder if that is why so many of our regulars have stopped appearing?

I just thought that they did not like the new forum.

I will let Andre know that this is an ongoing problem and maybe he will fix it. :)

Yes I did have a good trip to England, thanks :)

I was hesitant to include this post because I do not want people thinking I am big noting myself.

I noted that there are a number of mathematicians working the forum and some are much better mathematicians than I am. (I do not know all their qualifications but I know by the work they produce)

It is just that some of the question askers are wondering about the regular answerers' skills and I do not think it hurts to satisfy their curiosity and let them know that they are dealing with very knowledgable people, who are also being very generous with their time.

I would have answered at least some of these earlier but they disappeared!

It was really weird. I thought I saw one very early today but when I looked for it later I could not find it - and I spent a fair amount of time looking too. This happened to me last time Mellie posted too. I look for icons, maybe her icon does not always display? It is a real puzzle to me. Anyway, none of these have been answered yet. Maybe they were hidden from other people as well ???

It will be so much better if Mr Massow reintroduces our ability to search for a user's posts via their member page or the search feature.

I think this must be ther return of the old members week! Is that because December is nearly upon us? Lets see, Anonymous4338 has been back for a week or so, DragonSlayer554 returned yesterday, TitaniumRome made his presence felt today. You three, along with Riddles, Olivia4.14... and Hayley if she is still with us could try and boost the young crowds interest with riddles, puzzles, and quality social threads. Along with your standard questions and answers of course.

Also Dbg4thebest has posted a new Music report. I would really like members and guests to support him please. Thanks Denzel The post is with the interest posts below. :)

It is very important to be very vigilant in any social setting and the internet is certainly no exception.

Please be very conscious of your own safety and of other user's safety. Never give out personal information and do not be tempted to leave the forum to chat via email or facebook. Socialise within the forum or with private messaging.

If someone makes you uncomfortable, DO NOT RESPOND TO THEM ! And let me or CPhill or Alan know about it.

Some posts on this thread rang alarm bells in my head. Please **READ** what i have written within the thread.. Some of it is repeated but not all and it is important for all of us to be reminded of all this over and over again!

Forum / answerer considerations. Thanks Riddler

Please add your thoughts.

The forum is doing some really weird things.

Sun night, when I tried to remove threads from my watchlist, and once when I wanted to post a new solution, the thread was downloaded to my computer instead.

And then, my wrap lantern from Sunday, which was still there (whenI paste the address straight into the address bar)

http://web2.0calc.com/questions/wrap-lantern-sun-29-11-15

Was no where to be seen in the 'questions list' - Today it has returned again. ://

This happened to me once before when I was looking for one of Mellie's questions.

Also some of the posts are displaying and then going blank later on. Anonymous4338 gave a detailed answer to a question, and then the question disappeared. I mean it was still there but it was just white space. And I saw other threads like this as well. Weird!!!

Also the picture insert was not working. I have seen some recent pics, maybe it is working now or maybe members have been following Alan's instructions on how to post a pic when the normal method is not working.

**Hi everyone,**

Well the forum is definitely alive with members and activity. There is no way that all questions were answered or that all answers were checked. As desirable as this would be it is totally impossible on our busier days. :(

Anyway we have lots of dedicated answerers which is fabulous. Today these were gabbifluker, LambLamb, CPhill,Alan, Hayley1, Anonymous4338, HaleyWoodall17, Riddlet, buubleman, GenericUserName, Saseflower, xXForeWraithXx, and Heureka. Thanks everyone.

**Etiquette for social posting**

Social posting is fine but you need to keep these social posts to a small number threads.

The vast majority of threads must be used for mathematics queries. If the forum is clutterred with social content then the real questions end up getting overlooked. I have written more on this in the post below. Please read it

If people persist in creating new threads instead of posting on the end of ongoing threads they may find that their posts are deleted. You can find the current existing threads via the 'answer' page tab :)

At the end of my wrap posts I include a hyperlink that takes you back to the Wrap lantern for the day. I like people to talk to me about the wrap - or just chatter to me in general **but could you please do it on the wrap lantern instead of here.** Otherwise this thread just gets toooooo long toooooo quickly.

This thread is just for the wraps AND for important forum issues that you think people should be aware of.

So if YOU have an imprortant forum issue to bring to people's attention then by all means post it here OR post the address of the thread here. (the address of where you have started a discussion of the issue)

Thank you

Yesterday Mr Massow fixed out **picture posting** problem so it is easier again now

Here are the instructions: https://web2.0calc.com/questions/instructions-on-uploading-pictures#r4

AND

Today I was looking at some brilliant **LaTex** that Heureka had posted and I realized that if I right click on it then I can view the Latex in an expandable box AND I can highlight it so I can copy it. This is fabulous. For me the only way I increase my LaTex knowledge is by learning from others others (mainly Heuraka and Nauseated). So this is a really great forum enhancemant. Thanks Mr Massow.

I did notice something this morning

There used to be 5 forums here: English, German, Spanish, French and Russian.

I knew that the Russian forum, which was not being used, was removed a while back but I noticed this morning that it has been replaced by HINDI

Hindi is one of the official languages of the Union of India and it is the first language for 180 million people.

My goodness that is a lot of people !! Australia only has 24 million people! I digress........

We have many Indian members and guests on the forum. Perhaps some of those can get some good use from the new Hindi Maths Forum. Thanks Mr. Massow for organising this forum for the 180 million potential users. It will be great to see it come to life.

I will now take this opportunity to talk about this problem of obnoxious posts and posters

**A person who makes these unpleasant posts is looking for a reaction - any reaction!** As soon as you put words into a reply post you are giving this person exactly what they want, you are giving them attention! If you do not respond at all the person can derive no reaction thrill. It would feel to him like he is trying to prod a brick wall. He'll get bored with that very soon and go find a different playground that might be more fun.

Often it seems more like a bad episode of "Days of our Lives".

Anyway, she has nominated a whole heap of old historical threads. I asked her to nominate just one but maybe she did not understand me properly or maybe she just got caught up in all the excitement. Anyway, here is her post of threads that she nominated for tonight.

**Good day to you all,**

I have not done a wrap since Sat 20th Feb 16

I have not been on the forum much, I am just too pre-occupied with other issues.

I have not been keeping lists of names, sorry.

**Forum News:**

Mr. Massow has continued to make changes to try and make the forum better for us. There have been some positive changes, for instance, it is now a little easier for the moderator to get rid of garbage posts and we can close threads as well. Most decent people who use the forum understand the need for moderators to be able to delete or hide offensive posts.

We are supposed to be able to edit our posts. This facility has not worked for perhaps a couple of weeks. Anyway I have written to Mr Massow and asked if he can fix this. I have not heard back as yet. I am sure Mr Massow is very busy, but I will remind him in the next couple of days if I do not hear from him first.

**Camelot News:**

**Good day to you all,**

I have not done a wrap since Sat 7th May 16, and that was the first one since Feb 16.

I stopped doing them because the forum got too big and I was too busy with other things.

At this stage I do not intend to start them again on a remotely regular basis but there were a couple of interesting post today and I just wanted people to see them.

I am sorry, I know many of you post and answer very interesting questions very often and I do not even see them anymore. I am sad about this. If you send them to me by private message and I have time I will post them in a wrap for you so that other people can see them too.

**Forum News:**

I was just reading my last news entry and the problem is the same. Most people cannot edit their posts! This is a real pest and it is one of the reasons that I stopped writing the wrap. Collecting the questions just became too difficult when i could not edit the thread that they were entered into. Soon I will apprach Mr Massow about this again but being realistic the problem is not likely to go away.

**Camelot News:**

Camelot seems to have been defeated.

The King is still off at the crusades. Queen Guinevere has not been doing a good job of ruling in his stead. The ghost has been silent. The Doctor, Morgan Tudd, has not been seen in months. Sir CPhill and Sir Alan are here but they seem to be in disguise. I have heard no more news of Sir CPhill's search for the Roman Zero. He knows it is in Sisyphus's boulder but still he has not retrieved it. I did see Mistress Katie Leigh recently but she was vas very quiet. I did not even hear her school keys jangling. Maybe our reporter HeatherF, is off soing war correspondence with the King. I have not seen her.

**Mathematics posts: **

I am sure that there has been a great many excellent questions and answers but unfortunately I have not seen them. :(

1) Max posted this one and Heureka and I answered it. Thanks Heureka :)

http://web2.0calc.com/questions/sequence_14972

2) This one was asked a while ago and I have been talking to Bertie about it. I really like the explanation that Bertie gave, I think other members could learn from Bertie's answer too :)

Plus, I always find these combinatory questions interesting.

http://web2.0calc.com/questions/plz-help-me-fast

**Repeat offer:**

I know that there were other good questions and ansswers but I have not collected them. Like I said, I invite people to send the addresses of good questions/answers to me by private message and if I have time I will include them in a wrap like this one. They do not need to be high level questions or answers, they just need to be interesting questions, or answers that you think are worthy of recognition. They can be your own answers or someone elses.

Please take advantage of my offer
