As we know, Codeforces is a big website with a lot of features. And it may takes several months or years for some newcomers to know how does Codeforces work or how to do something in Codeforces (like creating the mashup). But sadly Codeforces doesn't have a help center or tutorial for them, only in some blogs which is hard to find. So I think creating a Wiki is necessary. It will be good for both newcomers or old users.

Here are some advantages:

• Help newcomers to understand and integrate into the community.

• Help Codeforces become a better and more perfect website.

• Help users to find the way to solve the problems they met quickly.

• If we set up the Wiki on other websites(like Wikia) it won't cost Codeforces a penny.

• Everyone can share his/her ideas.

I think it's a good idea, what about you and MikeMirzayanov ?

UPD: Thx for your support! I have created a Wiki here on Wikia: http://codeforces.wikia.com/wiki/Codeforces_Wiki.Help the Wiki get better if you can! Thx again! If you have suggestions tell me plz!

(Don't tell me off only because I am not sending blogs about contests:D)
