Re: importing bb_users into wp_users
The reason that happened is that the user roles are stored in a separate table. If it is an integrated site, they are in wp_usermeta (or bb_usermeta if not integrated) where the meta_key is
bb_capabilites and the meta_value is the capabilities assigned to them. I have no idea what the syntax for these capabilities is. However, if you wanted you could go into the database and search for the user ID that you are changing, and just change it there. Otherwise, reassigning the role might be just as easy, though it will still leave the record in the usermeta DB for that ID number, which might cause some problems. Unfortunately, there just isn’t an easy way to do this.
