Sorry to kinda derail but seeing vBulletin was mentioned above, why is Burning Board better then vBulletin?

vBulletin allows for user-customized titles, and the admin can prohibit specific users from taking advantage of that option. So if you had a forum member who consistently picked a title that the admins did not like, they could simply reset it and remove his privilege to change it (as an alternative to harsher penalties, of course). (edit to clarify- I'm not saying that this forum runs on vB, just using vB as an example)
