Nickname configuration on servers

Hii,

I have a suggestion which affects the nicknames on servers.

The "problem" I have with it is that I'm not amused about the fact that the server owners / rules can rename me there. At the moment you can rename others by give them stupid names and the person who affects this can't do anything against this. Only solution: leave server.

It would be better if I can rename me myselfe for every server I joined specialy.
