The best thing to do would be to read over the RP sections rules, and look through some of the RP threads that are going on. It's kind of a watch and learn type thing, and if you need help past that, then try PMing the RP area moderator, Alter Ego.
Since this area is for newbie intro threads, and not question threads, I'm gonna have to close this up now that it has a bit of an answer.
