When you want to claim a server to be your own, Gametracker will ask you to change your server's name to "GameTracker". This proves if you are the server owner. You can change the name via RM/SM or your server host control panel (if you rent it). GT will then scan your server; find the name has been changed, and give you the rights to the server.
