*feeding all the hangout members' knuffels*
I generally do that for one-on-one RPs. Here's a sample:
[x]For group RPs that I've done...or at least the one I was modding, it was a whole forum, and I checked and approved profiles for the RP to make sure that there were no Sues and that their character would fit the plot. There were over 200 members at the time and eventually I turned over the task to someone else. :X I would RP with almost anyone back then though, but it wasn't a romantic RP. It was like, those magical school ones. XD We had RPers of all skills and people came and went and there were in-game events and stuff. It was really fun.
I won't make myself RP with someone if I don't want to, though. :X I RP because I enjoy it, and if the other RPer is a jerk, I don't care if they are the best writer in the world or their character is the most awesome character ever (literally, not sarcastically). I don't put up with a lot of shit in RP.
