well today like any other day i was working when one of my friends came to me and asked if i could give him an ID so he can use the network localy,he asked it would be as restricted as possible (i knew what he was up to) so i logged as the admin and went to setting ,user and password,and tried to add a user with the username "restricted" but to my great surprise a warning message poped up with somthing like this:
The user restricted already exists
but i did not have that user in my users list,dose anyone know why this happens?
