crossovers100 is the crossover version of fanfic100. You lay claim to a character/pairing/general fandom and write a fic off each of 100 (well, really, 95; 5 are author's choice) prompts. If you want to cross the same two characters 100 times? You can. If you want to write a different fandom per crossover? Go for it. Only requirements are 100 word minimum and that you *started* from the prompt, not that it's necessarily anywhere to be found in your fic.

::faintly embarrassed:: At the rate my stories keep growing plots, I'm going to be a decade finishing these.... But Vanzetti dangled it in front of me, and it's fun, so hey, why not?
