book clubs

Just wondering does anyone join any online book discussion forums beside this one? I just joined The Cult which seems pretty good.
Any other good forums or clubs? THX :D

I joined a few different groups on myspace.com. Mostly sci-fi/fantasy book clubs. I am sure that there other areas of interest a well though.

I have done Crafter''s CHoice a couple of times.
I have built a pretty good library that way.
