Mandatory Profile on Fedora 9

[Bravismore Mumanyi]

Can someone help with how I can possibly go ahead and create a mandatory 
profile for a public user account. I am managing public computing in a 
library and would like users to use one common account. However, other 
tech-savy users delete shortcuts and menu items to confuse starters. I 
would therefore want to have this common account with preferences that 
no-one except 'root' can change.

If there is a way to automatically log-on the account on start-up?
