Any old/active member can change his nickname, if you want to change your nickname send a PM to the administration (Mods, Team Leaders or The Administrator)
Ps: you can not change your nickname for the fun of it, or change it every couple days, the administration reserves the right to reject any renaming request and might ask you to register with a new account.
