Comment 1 for bug 522811

you mean you change both your nick and CID? how is the hub supposed to identify you if both nick and CID have changed? sure, it could keep track of all previously used nicks but that is a bit too much... it should be up to the user to know what nick he has last used.

there is a setting, +cfg allownickchange, to disable this ability of regged users to change their nick if this feature is annoying.
