Ooh, I had forgotten about that! Thanks! That does indeed help--sure enough, Anybody's Baby is indexed there. That should help with most of them.
However, I know there are a few fics that go straight to the Archive, bypassing the MBs--there's one author who does that a lot, I think (the name is niggling at the back of my mind, but I'm having a hard time remembering). What should we do in those cases?
