Yeah, I've tried the samething. My original name was SpazTheDog, then Poleepkwa, THEN Spazzy. That was back in the older cRPG.
This time I was planning on changing from Spazzy to: Poleepkwa_The_Deadly.
Though, it seems now that the name changer is only for fixing Typos, and adding clan tags to prevent those who hop on and TK, troll, etc from changing their name to have a clean reputation, then repeat.
