I used to do the online roleplay stuff a lot. Mostly Livejournal and AIM. Do people even do that anymore?
Anyway, now my roleplay is more in tabletop gaming. I play D&D and the ASOIF RPG with a tabletop group at my school. D&D is really combat heavy, so RP isn't a huge aspect of it anymore, but ASOIF is super roleplay heavy. Pretty much everything you do is RP. One guy in my group does hilarious voices for each of his characters, and another guy just sounds like Deckard Cain from Diablo (even though he's trying to sound like Bane)
