ADDRESS OF ORIGINAL WRAP!

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

 

Address of yesterday's wrap post.

http://web2.0calc.com/questions/all-questions-answered-to-this-point#r492

 

I have decided to start a new wrap because the old one is getting difficult to work in.  

 

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 since then.  

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

There are now 493 posts on that original thread, it is sad leaving it behind but it is not working well any more.

Good evening all,

 

Great answers today from Mellie, Shaniab29544, CPhill, Zegroes, TitaniumRome, Lonefish, DarkBlaze347, Civonamzuk, Natthada, Badinage, Money, YaBoiWinz, At00B11, Zacismyname, Sasini, Heureka, Alan, and MathsGod1.  Many thanks to each of you :)

 

It has been an excellent day on the forum today.  Zegroes dropped in and the the forum became very animated for a couple of hours.  It is great when this happens.  Chris and I really appreciate it and a number of our members were joining in.  MathsGod1 and Mellie were quite enjoying themselves I think.  I think Badinage was watching at a sensible distance.  I am sure others were haveing some fun too.  Zegroes is like a cyclone (tornado) when he drops in to visit.   Thanks Zegroes, here is a smiley just for Zegroes, he always complained that I did not use them enough.       

Thank you everyone for all my wonderful birthday wishes and my fabulous cake too.  I've had a great couple of days. :)

Hi all,

 

This is a historic day. The first day of our new wrap thread.  It would have been nice to start it on one of the forum anniversary dates but they are all too far away.  

It is my birthday today but that is almost a coincidence.

 

As always there were many great answers today.  These were authored by SamHenry, Bertie, CPhill, Badinage, MathsGod1, Natthada, Geno3141, sasini, Civonamzuk and Heureka.  Thank you, you are all wonderful. :)

Hello,   

 

Today our wonderful answerers were Alan, Zegroes, Brodudedoodebrodude, (your name shall hence forth be Brodude), Gibson338, Zacismyname, Geno3141, Zectico, MathsGod1, TitaniumRome, Badinage and Heureka. 

 

When people repost in the manner requested (giving the address of the original post) could answerers please answer on the original thread. You could also make a note on the new thread that you have done so.

This way the question and all the posts relating to it will be together. :)   Thank you  

 

Oh, today I stated using the '?' icon in the left margin to indicate which questions I wanted to go back to, some of which were unanswered.  I have a couple of these symbols available to me.  Would anybody like to suggest how they might best be used?

Alan, you seem to be best at finding your way around.  Can you (or someone else) work out a way to bring up questions with these symbols using the search feature?  If you could that would be great :))

The icons are called: 1-question, 2-exclaim, 3-mrgreen, 4-alert

Hi everyone,

 

Great answers today from BrittanyJ, CPhill, Alan, Civonamzuk, Badinage, MathsGod1, MasterGrimm, Geno3141 and TitaniumRome.   Thank you   

 

If someone makes an unpleasant post I strongly believe it is best for others to ignore it.  If you respond  in any way then you are giving the poster the attention that they are craving.  If they are ignored they will get bored very quickly and go away.

There has been a lot of very inappropriate material posted on the forum the last couple of days.  If you see any of this could you please let me and/or CPhill know straight away by private message. Please copy the address of the post and paste it into the message so that we can go straight to it.  We have the power to delete it.

Please do not publicly respond to these post !

 

Please everyone,  this 'End of day wrap'  thread is just for the wraps.  If you want to comment or leave posts relating to it could you please leave them on the lantern thread.

A good day to you all   

 

Our excellent answerers over the past 2 days have been;  Mellie, Geno3141, Heureka, Alan, MathsGod1, TheJonyMyster, DarkBlaze347, CPhill, Michael14, IlovePi, Rosala, Gibson338, DjRelic, Evermornin17, Lacrossegirl2, BrittanyJ and Yoloxd.  Thank you all.    

 

Today I have been in contact with the owner and developer of this site, Mr Massow.  I mentioned only a couple of issues, the main one was the unwanted pornography that has been invading our site.  I asked him if we could make this a members only site, he did not respond to this, I know it is not what he wants but he says he has been working on a website update for the past 5 months and it will be implemented soon.  

He also said that he has contacted http://www.webpurify.com/  to see if their solution can prevent unsavoury posts and images.  He is hoping that the webpurify solution can be easily incorporated ino the new updated forum. 

I will keep you updated on any further communications that I may have with Mr. Massow.  

 

If you would like to comment please do so on the Lantern thread.   Thank you.

A lot happened today but I will do the credits first:   Our fabulous answers were provided by Badinage, MathsGod1, Sean1w0ii, Alan, Mellie, Awesomeee, CPhill, DarkBlaze347, Heureka, Geno3141, SoulReaper222, Zacismyname, Dbg4thebest and Civonamzuk.  Thanks all.

 

Mr Massow contacted me today and said that these changes have been made.

* Anons can no longer post images or web links    * A simple swearword filter has been implemented

* Message system has been improved    *mobile calculator start page improved

* There was also a score update today.  Some people's scores jumped markedly and this is why.

Congratulations to MathsGod1 for gaining his 1000 point star.    

Improvements that are to come:

* Better filter    *faster page load    *better message system.

Thanks you Mr Massow  

 

This morning someone was impersonating me.  Admin noticed almost immediately and the member has been deregistered.  You must be very careful in any internet environment.  It is very easy for people to pretend to be someone that they are not.  You as a user must be very cautious.  Do not be too quick to believe people.

Some people have noticed that there is a CPhill and a CPhill2.  Do not be alarmed, they really are the same person.  There are a great many messages between me and CPhill and this is causing problems for us.  So the alternate name CPhill2 was registered just so that we can continue to communicate with one another.

 

Now for the really BIG news.

Chris and I are delighted to announce that as of today ALAN will be moderating along side of us. 

Alan has been a member for over a year and his contirbutions to this site have been invaluable. 

We thank you Alan and we look forward to working with you for a long time into the future

Hello everyone,

 

It is great to see so many members give really good quality answers.  When I first set out to 'grow' this forum it was always my wish that eventually many of the questions would be answered by the members,  with the younger members answering as many as they could.  (There were no other 'older' members back then anyway)

Now this is happening and I am ever so pleased.  

 

Answer credits for today go to Heureka, Alan, Jhicus01, Carmelbowom, CPhill, HeatherF, Everymornin17, BrittanyJ, Isiber17, civonamzuk, MathsGod1, Ncolllie, DarkBlaze347, Brodudedoodebrodude, Headingnorth and Mellie.   Thanks all  

 

Oh, Mr Massow said he had improved the message system.  I have noted that messages are much easier to delete now.  We still have to delete them one at a time but we can start deleting a second and a third one while the first deletion is still processing.  This is great.  Thank you Mr. Massow.

Hi everyone,

 

I did not write a wrap yesterday so today is a big one.  We have so many wonderful answerers, and here they all are:  Martind, Cstaib45, Alan, Squaddy, DarkBlaze347, MathsGod1, HeadingNorth, CPhill, Nathan0501, Everymornin17, Awsomeee, SilkerR7, Civonamzuk, Zacismyname, Mihail, annabelle1DirectionS, Geno3141, Xerces, Fiora, EinsteinJr and MrGenius.  A big thank you to each of you.    

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

I saved this post for the wrap because it was extremely funny.

I have whited out a number of offensive posts that it did contain.

Volume of cube given the SA.         (Thanks Geno3141 for your great answer.)  

There is some very unacceptable behaviour on the forum at present.  

Nauseated was voicing his displeasure with his usual degree of mordant humour.

However, this is a serious matter, if the offensive posts and private messages from members continue THEY WILL ultimately result in account suspensions.  

Members are expected to be civil to one another at all times.  Also, this is not face book or a games site.  

We all want everyone to enjoy being here but this is fundamentally a serious forum for learning.

Hi everyone,

 

My last wrap was 3 days ago, that is because the forum was down for nearly 2 days!  

There were major database problems and the whole forum went into read only mode.

Mr Massow had the system operational again yesterday.  Three of the databases were up and running and he was working on a 4th one when quite suddenly the system shut down again.  Anyway, it is working again now except that our point scores are all over the place.  Peoples scores have been fluctuating wildly all day.  Do not get too upset, you will most likely end up with your original score or a score that you are happy with.  It is probably just a problem with the data base.

This happened last time the system had a major overhaul (about 13 months ago) It continued for quite a while before it settled down.  I thought it was admin trying to work out the best scoring system.  Anyway, eventually everyone got used to haveing a different score every 5 minutes and people started seeing the funny side of it.  You should try not to put too much importance on your score anyway.  You are here to learn and to enjoy the environment.

 

Our incredibly intelligent answerers over these few days have been MathsGod1, Rosala, CPhill, Radix, Baneofwizard, DarkBlaze347, Thejamesmachine, Dbg4thebest, ProxyGOd, Civonamzuk, Zacismyname and Didig.  Thanks all    

 

I almost forgot - Rosala has now been with us for a whole year!   Happy member day Rosala!

This wrap is super late today and that is because I was in Central Sydney to see the Vivid.  This is a Lazer Light show that runs for about a week at this time each year.  

Here is the web address, it will give you an idea of what it was about.  The pictures on the buildings are all animated. It is quite brilliant.                   http://www.vividsydney.com/

Hello everyone 

 

It has been a very quiet Wednesday, but there has been some good questions and these were answered by Civonamzuk, Radix, Alan Heureka, Syllogist, MathsGod1 and DarkBlaze347.  A big thank you to each of you.  

 

I just remembered. Some people are experiencing a  survey pop-up that relates to this site.  The owner of this site knows nothing about this.  It is NOT genuine. I advise you NOT TO click into it!

Thank you MathsGod1 for bringing this to my attention.

Hi everyone,

 

This is my first wrap for 6 days, I am not sure if anyone cared, the forum has been very quiet and I do understand that everyone has there own take on which questions are interesting and I know most people are only interested in their own question.  

I do like to give answerers credit for all their effort though and I know some people do appreciate seeing their name mentioned in here.  

 

Anyway for these 6 days our much appreciated answerers have been Sir-Emo-Chappington, CPhill, Alan, Geno3141, Heureka, MathsGod1, Radix, Panda298, TitaniumRome, Shaniab29544, Fiora, Badinage, Xavierbester, Rubii and Dbg4thebest.   Thanks guys     (that includes the girls) 

 

If you would like to comment on any site issues please do so on the Lantern Thread.  Thank you.

I am told that the U.S. students are starting back at school after their summer break so the forum should be getting busier soon.  Too bad I like it quiet but even I know there are some distict advantages when it is busier.  The social posts are better just for starters. :)  TitianiumRome has had to hold up the social posting almost entirely by himself and a great job you have done of it too TR.
