There is a glitch with vBulletin and vbseo that will now allow certain users to view your profile because of a period or dash in your username. Be advised that any username that has this in their name will be changed so that it no longer has those specific characters in it. It will have a space in it instead unless you tell me otherwise how you want it. For example, Sgt. Slaughters username is now Sgt Slaughter.
