I wanted to stop particular user names appearing in the list of names at the log in screen. I remembered reading that this could be achieved by changing the user id of the account to something less than 1000 (I think I made it 990). So I did this. That worked fine, but now when I wanted to change it back, the name is not appearing in the list of user accounts in the
users and groups menu under administration.
How do I modify the phantom account?
