Ninja has completed his first draft of 'Great Answers to Learn From' and he is looking for comments and input from other members.
You may want to suggest that another thread be included.
You may want to suggest that a thread be moved from where Ninja has put it to somewhere else. Remember, Ninja has not done a lot of these topics so it is possible that some things are not in the best places.
You may have something else on your mind that I have not thought of.
I am very pleased with the thread that Ninja has put together. It is very nicely presented and over the course of time I feel sure that it will be well used.
Ninja, On behalf of web2.0 forum I offer you a very big thank you. Rosala might have some roses for you if you are really lucky.

Hi everyone,
It was not that busy today but there were some great answers delivered by Rosala, alan, CPhill, Zegroes, Kitty<3, Heureka, Stu, AzizHusain and DeviikaAnand. Thank you all.
AzizHusain and DevikaAnand are new. Welcome to our web2.0calc forum. We hope that you like it here.
I thought I would talk a little about the numbering system on threads.
A thread title is allocated when the original question is asked. The first answer post has #1 written after the name. The second answer post is #2, the third is #3 etc. At least I think that is correct. Anyway if you want to refer someone to a particular post, rather than the whole thread, just click on the title of the post that you want. The address in your browser will renew, giving the address of the post. You can copy that address and post it as your reference address. I think that is all correct. I hope I have used all the correct terminology.
Today mari379 asked "How do you get points" Here I have explained my attitude to the allocation of points. CPhill and Zegroes and Rosala have also voiced opinions.

If anyone would ever like to recommend a good post to include in this "End of Day Wrap" could you please send it to me via private message. The forum is not very busy now while most of the US schools are closed for their summer break but even so I often just tick off posts without really looking at them. I could easily miss outstanding posts so please let me know if you see any really interesting or impressive ones. When the forum gets busy again this will become totally necessary for the proper running of the forum. I may provide a thread for you to place the addresses in. But for now private messaging will work fine. Thank you.
Now for some interesting posts:
1) Here Alan has employed the Taylor Series to evaluate a limit (actually, to find a derivative)
Thanks Alan and thank you Chris for recommending this thread.

2) This looks interesting - Pretty picture too. Thanks Alan.
3) Lets end the day with a laugh. That is a great idea Rosala. Thank you.

That is it for this Wednesday/Thursday. Goodnight

Try it this way.
Think of negative numbers as cold and positive numbers as hot.
So -- is taking away cold. What happens if you take cold away. It gets hotter.
So -- is +
REMEMBER it only works this way if the 2 minus signs ars do close together that you can put a circle around them with nothing else ion the circle.
3--7 = 3+7 = 10
