Yeah, that was what I was referring to. But I actually just decided to register it so it doesn't matter now anyways XDHe probably hasn't registered it and just uses it for his name since you need one to battle. But anyway, if anybody would like to have a battle I should be online for a few hours so just PM/VM me.
Also, I'll be on and off PS throughout the day so if anyone wants to battle me, my username on PS is Professor Plum.
