advice? take a tour...ok, wait, you already did that. Depends what your particular poison is, but umm, my advice would be to jump right in and join an RP, or join a thread, or post some idea on the main site, oh...wait, you mean general advice? Ok.
There are people here who throw monkeys, hit other people with frozen trout, and apparently have access to a cache of flame-throwers. Be wary of them!
Oh and WELCOME M1911!!
