yah. old site is good.. i want change it .... help us to know about it....!

You mean the in-game nickname or the one on the forum?
If you want to change your in-game nickname, just launch the game, and in the logging in menu click "create new account", select a new nickname but keep your old password and email address. I've changed my nickname twice, first time was back when gamesas website still existed and i couldn't log on it with my old name. When i changed my nick for the second time gamesas was gone and this website lets me log in with my old nickname even though i'm using a different one in the game.

no i want change my forum name. multiplayer account name.
