I have purged all the inactives, and reassigned (or generated a first assignment, as the case may be) books to all who requested one.
I don't think my purge/reassignment script screwed anything up, but everyone please check
the list and make sure that (1) If you requested to keep your previous assignment, that it is still listed as your book; (2) If you requested a new book, you got one; (3) You don't see anything else that looks wrong (like a review that disappeared or something).
Enjoy!
