Root Commands

I am trying to use a form (password protected of course) that will allow an administrator to add POP accounts to a linux box. The problem that I seem to have is that the form is trying to give the commands as user 'nobody' and they need to be given by either root or a superuser. Is there any way to accomplish this? If somebody were to point me in the direction of a tutorial on this subject I would really appreciate it. Sincerely, Patrick Armour www.greatplainsinternet.com
