This plugin allows you to create multiple levels of Super Admins in a multi-site configuration.
It is entirely possible that there could be serious bugs when used in different settings. At this time, I am seeking people to test the plugin, so please report any issues you encounter. Thank you.
Also, if you are updating from the original public alpha of this plugin, you will need to delete the old version before installing this version. The folder name changed from extended_super_admins in the initial release to extended-super-admins in newer versions.
If you downloaded and installed this plugin from the WordPress repository, you will not need to do so, as the folder name changed when adding this plugin to that repository.
This plugin requires WordPress. It might work with WordPressMU versions older than 3.0, but it has not been tested with those.
This plugin requires WordPress to be setup in Multi Site mode. It will not do anything at all if the Multi Site functions are not enabled.
This plugin also requires PHP5. Some attempt has been made to make it compatible with PHP4, but it has not been tested in that environment.
