In a persons profile, it will show previous user names. Question: If I were to change my name, does that open up for someone to use my previous name? That is lets say I change my username to something that I only planned on using for a short time and planned to change back - could someone create a new account and "steal" my old name since I was not using it at the time? Or now that it saves it in the profile, do it also protect it?
