Adding Users to Existing Groups in Ubuntu (Oneiric Ocelot)

Hi have been working in Virtual Box, this days and need to add my user to the vboxusers group. I was going to do it graphically, and suddenly I notice that the application I use for doing this job it disappear. :( So I have to use the CLI If you know the group just do this Steps sudo usermod -a -G GROUP USER where -a means append. Add the user to the supplementary group(s). Use only with the -G option. If you want to read more about the usermod do man usermod If you don't know the group Steps groupmode 2 TIMES sudo usermod -a -G GROUP USER If you see the only difference is that you type groupmode and press tab 2 times and all the groups will be display. HOPE it works
