Help: Nonmoderated Username Bold
 

I have a problem with our message board after it was merge along time ago from another non-vB board. The problem is some of the members username is bold, when they aren't moderating any forums at all. On the user group they're under "registered" member, but their screename is still bold. Me and my partners been trying to find away to unbold them. We even used the "Username Merge" hack to merge their old account to a new account, but their screen name is still bold. Does anyone here have the same problem or know what the problem is and how to fix this problem? The last thing we can think of is to delete their username and start a new account, but they might not like the fact that all their posts will be deleted.
