OK! How do I do my signature?!? I found out how to make my ticker but I can't figure out how to put it in my posts automatically. I saw someone who had a signature after only 8 posts. I'm jealous. I want my own signature!!!

There shouldn't be anyone with 8 posts and a signature...signatures are available only after 30 days and 30 posts, due to problems with spammers.

Stick around! You'll have it soon enough if you stay here and get going.

Actually these are quite new rules. When I joined a month ago, I only needed 30 posts (and not 30 days). The person you saw with 8 posts may have joined several months ago (or years ago) when the rules were different.
Sorry you have to wait, but I hope you'll stick around and keep updating us with your progress!
