I couldn't figure it out either. Stoney will have to check it out later. If he can't rig it so we can change our own usernames we'll have to PM him to do it, I suppose. >.<
I replied here but somehow that reply doesn't appear.
I meant to say that V Bulletin doesn't allow members to change their usernames, only admins can do it. I think.
It's probably not difficult to do. So PMing StoneTable oughta get the trick done relatively fast. Sucks not to be able to change them ourselves, but them's the breaks. ^_^
