I've been pretty lucky, mostly because I always write with people I already know who vouch for the game before I join up. (Plus I've only been in like... a dozen, total.) If you can figure out what genre you want to try I might be able to toss a link or two your way, by way of some of the aforementioned friends. Or, failing that, I can probably talk some of them into creating something for the same purpose; a lot of the people I know are mods.
