Ok this is getting really frustrating....!
I need to have files out put that will:
(1) Allow new users to login as guest/[or new user] and Add new listings and not edit existing users info.
(2) Allow existing users to login and edit there own files and not other users.
(3) Allow Admin to edit/view all { ok so this works fine }
(4) Add current date and time to a 'LastUpdated' field when user edits info.
(5) generate a unique 12 character UserId when new user is added.
Now I've tried figuring this stuff out for days now; and while items 4 & 5 are currently unique to my needs I'm sure others would like to know about #1 & #2 above. I could be missing somthing this being only my first pot of coffee of the day.
