Just installed GW--how do i set up an email login/password?

I just got my preorder in the mail and i am trying to play. Once the game is started up it asks me for email login/Password and i dont have one... dont know where to get one... and/or may already have one and just dont know it. Can anyone help me out or post links of where i can register for this game. Help is greatly appreciated. Thanks!

well in the game ther should be a "create account" near the login button. Then you have to put in your key and stuff.
