First off, this is not a in-character roleplaying community. If you're looking for a place to play your Avatar characters on LiveJournal, try atladressing, avatardressing, or one of the many panfandom dressing rooms/roleplaying communities. However, if you're looking for a place to talk about experiences in Avatar RP, discuss characterization with people who play the same characters that you do, or find a roleplaying partner/group, then you've come to the right place! This comm is out-of-character discussion about any and all aspects of Avatar roleplay, and any and all past, present, and potential Avatar RPers are welcome to join and post.
As for rules... there really aren't any. Still, I am asking that you keep any and all wank OUT. If you hate the way so-and-so plays such-and-such a character and think they need to GTFO the internet 4ever, don't make a post about it here. (Basically, the only rule is that you don't treat this place like the Avatar version of bad_rpers_suck.) Obviously, I'm not banning people from disagreeing/debating, but flame wars are a do not want. The same general idea goes for pairings. Talk/debate about them all you want, but don't tell someone that their pairing sucks or that they're being OOC just by playing it out.
