I recently moved to a new company, and my user name for the DUG community is with my previous companies e-mail address. It appears that I do not have the ability to change my user name once the account is created. It would be nice to have that ability to change since users may change companies from time to time.
NOTE: I am able to change my contact e-mail address, so I can still get notifications. I just have the inability to change my user name.
