Although not necessarily. If you're useing PHP-Nuke, you can set an Admin based on either Super User (basically GOD, but your main account can never be altered by another admin, I think) or a Admin of specific "modular" modules. The "modular" modules have their own self-contained Admin sections, like the Forums does and a few of the others. They are the ones that show up in the second section of your Admin panel for PHP-Nuke.
