Is there a way to change the nickname without changing the rest of the registration? Currently the change requires new registration.
Sometime a person may get tired of the nickname or it may be inappropriate type or whatever.
Just to note about the future ability: all past screen names will be listed in your profile, along with the range of dates the screen name was in use. And, for X (7-30?) number of days after the name change, your "former" will be printed next to your current screen name. That will be done to discourage people from "hit and runs".
