Just as a bump / update, I'd like to mention that I'm interested in group RP stuff as well, including mature / 18+ groups. Before you tell me that those aren't allowed on here, I'll point out that you can have a group involved in a private convo and that it can work quite well.

Anyway I've got a few ideas for such groups, ranging from more traditional sword & sorcery settings to some more strange ones, including one that involves mechs. By all means, please ask if you're curious.
