Create Multiple Levels of Super Admins for WordPress Multisite
WordPress roles and capabilities are fairly rigid when it comes to the Super Admin – it’s all or nothing. What if you want to have a user be a super admin on a more limited basis? Extended Super Admins is your answer. It’s a plugin that allows you to revoke specific privileges from any Super Admin on the network.
Essentially, it allows you to create new roles within the site and then assign any Super Admin to that role, removing the privileges you’ve selected.
Just to be clear, the Extended Super Admins plugin cannot grant any new privileges. At the present it is only capable of removing privileges. It was written for the University of Mary Washington website and is compatible with both the WordPress Multi Network plugin and the Networks for WordPress plugin. Install Extended Super Admins and you’ll get more custom control over roles and capabilities when creating multiple super admins.
