http://askubuntu.com – I love this operating system (Edubuntu 11)!!! First time deploying it in a school so details would help. When I run the live CD on the server the clients that connect receive a log in screen with a button to log in as a guest. When I got the system installed on the hard disk it only allows the students to log in with there user name and passwords. Works great until faculty tried to use the computer lab for teacher training. Now I would love to have the button back and the ability to not have things retained after they log out. I tried to create a guest user with a basic password but only one c (HowTos)
