You just need to send a message to an Admin to do it. I had mine changed early this year, because I didn't care for the name I originally made when I first joined back in 2006.
1.0 Normal (Emrys)
0.1 Fire (Calypso)
0.1 Pied (Tessa)
0.1 Albino Kingsnake (Nienna)
2.1 Cats (Suki, Daisuke, and Kyo)
0.0.2 Leopard Geckos (Chi and Pixel)
Be very sure you want to change it though as we only allow one name change per account.
