What's so special about Asians? And what's so scary about your real name? It's not like there's a shortage of us doing that around the Net. ^_-
Anyway, I'm not in charge here, but there are a few places other than MOT you can hop on to. Quasispace is one. The link's on top. The other is ImproFicRoast (the link is also on top), our version of MOT over at Indie Madnesse. We're getting started to MST Eyrie's Hopelessly Lost in a wild IFR/MOT/Elmer Studios crossover. Feel free to drop by and contribute riffs once we start... just introduce yourself there first before you do. ^^
Oh, and as far as I know, Wanderer pretty much declared open season on the current Dave and Dyne MSTing. However, since you're new here, maybe you'd like to hang around first, try to get into the flow of things, and maybe post a few riffs on the chapters being MSTed. (No assurances they'll get in the final edit, though, but that's a given on all the jokes...)
Word of warning though: your intro could have used without the NOTE: first paragraph. IMO, you came off as whiny, pushy, and/or smart-alecky. That tends to irk off some of the people here. You don't get in by acting like a know-it-all or cry out "Look at me! Look at me!" I don't know how to explain it, but you *can* be accepted as a guest writer here without posting an attention-getter. You just have to act reasonable and mature when dealing with others... yet insane when you MST. ^_^
Of course, I'm nowhere near in charge around here. :P
Oh, and I'd like to take a look at some of those Mstings and comedic writings you've mentioned. Do you have a web site link? If you're interested in writing humor in general (and since you've done improv theater), why not drop by Indie Madnesse (http://indiemadnesse.sandwich.net/)? It's an improvisational fanfiction writing website (with some anime-based stories). All writers are welcome. [/plug]
