Well, I wanted to ask u, if u know of course - HOW TO CHANGE THE NICKNAME, I heard about this, so some people told me that I can change the nickname.
Of course it's not for free, but anyway - how can i do this?

Pm a admin tell him what you want it changed to, and then send him 100 000tc. And he'll change it for you.

Unless you mean in IRC in IRC just type \nick (nicknamehere)
Without the brackets to change your nickname.

FYI,

Course did not change the nickname, he just made a new account...
His original "Mamakal" is still there..
