How can i rename myself (forum and ingame)

I want to know how i can rename myself without loseing my permissions, rank or account.

Creat a new character, come to the server with it and do /login Antasma

You cannot change your forum name. Antasma, if you do what ThePunisher has told you, you will have to do it each time you join the server.

Dang, but i think i can live with that. You can close the threat now (if you want to, because i dont know why it should be bumped over and over again).
