Multi-Fandom Fan Fiction

Hmm. Part of me thinks this is a great idea, and part of me hates it, I think because most of the unwritten plot bunnies I've had are unwritten for a reason. Usually because they'd be very long and very complicated. :) Come to think of it, I'd say a large number of them also have at least the potential to contain explicit sex and/or slash, which I imagine you'd disallow. Which might actually be a make-or-break issue for me, because it's one thing to have rating limits, etc., imposted when you're writing to somebody else's request, and another entirely to be forced to write your own already-existing story in a different way than the story wants to go, if that makes sense.
