Hi,This seems a little extreme to me.
On the undernet now you can`t modify your username name.
A simple command or someting like that to be make ?
/msg x makeuser <newuser_name> <old_username> <yourpassword>
So if you don`t like your user any more and you whant to change it you don`t must to make a new one and ask peoples to give your access back on the new user.
To make more then one user is not allowed so this is a simple solution to change it.
Most people go through life with the same name.
On IRC you can easily change your name (nick).
Why would anyone need to continually change his username?
Just seems like a frivolous request to me.
