shananagin is accepting prompts for a DCU Femmeslash Porn Battle. You can submit prompts here, until July 18th! There can be Marvel crossovers as well. As long as one of the sides of the crossover is a DC universe. Anything with the DC Universe, so Smallville is definitely allowed.
I don't know how much of my flist is into femmeslash but if I recall, a few of you have said you are.
