Would you mind if I ran some of the post and member data rebuilding options now/soon? I'd like to see if that'll fix some of the incorrect usergroups and such but I thought I'd check with you first to make sure it won't break something or get in the way of something you're changing.

Not sure if that was the last version released though?
