I don't even keep track of plot bunnies, everything I have saved has at least half a page written (I actually recently went through and deleted several where I had completely forgotten what idea was behind that bit of writing). I have three different naming schemes for Doctor Who fic each of which is at least up to 12 under than naming scheme (before the deleting and including the few I've actually posted), plus a few that actually have names in their file name, plus a few for other fandoms.

One day I should finish something.
