My original username was Wilber7. It was that way for a while. Before the redesign though, Wade announced a username lock down which meant you would no longer be able to manually change your username (yes kids, we used to have that power).
Reason for the lock down was because people were changing their usernames and causing confusion on who was who. (Thanks again staff members for changing usernames like crazy, really helps keep track of everyone).
So I picked The-Great-One out of sheer fun and because I couldn't think of anything else.
