Thing 11 - is anybody out there?

I really like LibraryThing - as a book-o-phile with a penchant for the odd, it is really nice to know that there are other people out there with a fascination for fantasy and historical fiction that doesn't lean to the gory...but I digress. I wish there was (or maybe I've yet to discover) a way to create more than one library for the same user. I'd love to have one for my music classroom by age groups (primary/intermediate)as well as my personal library at home...I'm going to play with it and see what I can come up with. Because if I have to create more passwords, I'm going to lose my marbles!
