I\'ve set up phabricator and added several users. I noticed that I can change a user\'s real name or username, but I am unable to change their email address. Is there some
Administrators can not change email addresses because it would let them change a user's email address to their own, reset the user's password, and then log in as the user. Administrators are not all-powerful in Phabricator's permission model, and can not compromise accounts, act as other users, or violate policies.
If you need to change an address because you made a mistake when creating a new account, you can delete the account and recreate it.
