All the forums are open to non-members, so he can find his old post with out logging in, count the Es and Gs and then change his user name to log in.
Once its been changed, he then has to wait 21 days before he can change it again and its changed twice with in a day (I think).
He could have changed it to Gaythree depending on when he had went from 3Es down to 2Es, thats if he made that change him self.
If he did and that change was with in the 21 days, then he would be unable to change it to the Gay....you get the point?
Its clear its a Mod or Admin unless Aythree is able to hack the site and change it him self to create some intertainment for us.
