I dont know what you want from us Eric. Please stop writting with so big letters and different warningcolors.
I give you some answers even if I dont know your suggestion. There will be no way to change your nickname. We will give you the chance to create a new passwort, in one of the next RCs. There is no place where you can change your nickname.
The ban was not for your forumposts. It was for the posting of swastika in the lobby. Write your apology in the "I can not log in" thread and you will unbanned tomorow.
