I've installed Antix 8.2 base plus gnome via the meta-installer...I've also pretty much installed the rest of the gnome desktop environment.

In manage users and groups, only root shows up as a group in System>Administration.Users and Groups....I'm sure there is a setting somewhere but I can't find it.

I went in to add myself to vboxusers which I've done manually, but still __{{emoticon}}__ thanks!

EDIT: I found it....Applications>System Tools>Configuration Editor>Gnome-System-Tools>User>"Show All" to be checked.
