Well, that's what this hack is all about:
It removes the ability to change styles if you are not a primary member of the specified usergroups.

Use

PHP Code:

if (!is_member_of($bbuserinfo, X) AND !is_member_of($bbuserinfo, Y) AND !is_member_of($bbuserinfo, Z)) 


as the if-condition.
Or apply this hack (I really feel this should become factory code as it is needed often) so is_member_of() can check for several usergroup IDs:

PHP Code:

if (!is_member_of($bbuserinfo, X, Y, Z))
