Yes, i have both my own(The one i'm logged in as now) and the root user. And all the other strange users(cdrom etc.)
I understand the user system, because i ran textbased linux for about a month to learn more basic stuff about it, and i've been running Suse, Mandrake and Ubuntu, all with auto login, so thats not it...
There's just no users there... Veeeeeery strange
That is, what i think, the problem with the user friendly distros... If something is wrong in the Configuration menus, it's hard to figure out, because there's no verbose... But they are soooo user friendly and they look nice too
