I don't mind joining other RPs, mostly in the fantasy genre personally. Plot lines I am a tad picky about sometimes though. I can also adapt into other genres and whatnot as well, but I like to stick with my current array of characters to improve RP quality. Otherwise though, if my RP picks up, I have seen it get to the point where I had to spend 4 or more hours in a day for responding due to high volume of traffic on it, so it can become a part time job as the DM with my main RP setup.
