Help with gamespy please
 

Is it possible to change the name I am using for internet games or having multiple nicknames?
It looks like MoW cdkey is tied to gamespy, so in theory if I lose my account do I lose the ability to play online too?

I'd also like to know about this.

You can only have 1 account with 1 cd-key in MoW, your account is created on Gamespy which shares it with the IGN network.
So you can go to gamespy.com and edit your profile's nickname, once you did you can log-in with your new nick in MoW.

Thank ya!
