Hi.
The list of sub-forums in the DB side is not accurate on the http://www.talkbass.com/forum page since some of these sub-forums have been changed ("Bows" and "Rosin" have been merged together, "Music Theory" is new).
The EUB sub-forum was not created yet though. (I thought it was decided to create one, but maybe I didn't understand clearly...)

Regards,
François
