The ATS Users' Handbook contains information about things like how to get an avatar and a signature. You can also find it using the "FAQ" tab just under the ATS title bar above.
The Freshman Forum is another good place to get answers to questions newcomers have.
Feel free to introduce yourself in the New Member Introductions Forum.
TinWiki.org is an ATS-affiliated project to build a wiki-style encyclopedia for alternative topics. The TinWiki.org Forum (where you posted this) is really for questions related to TinWiki specifically, not ATS generally.
ATS is a really big place and can be confusing at first. Then you'll discover BelowTopSecret.com and be even more confused
But as long as you keep your postings within the Terms and Conditions of membership, you will find that people are more than willing to point you in the right directions, and that some real gems are hiding out in some of the more obscure forums. Exploration definitely pays off!
