Extension:SharedUserRights

What can this extension do?
This extension allows you to setup user rights that are taken into effect over an entire wiki family/farm. This is ideal if you want to do something like wiki hosting, or manage a family of wikis for yourself, a business, your school, etc.

Usage
Simply follow the installation instructions below, and make sure you add the necessary require_once line for every configuration file of the wiki family. Please note that for this to work, you must be using a shared database ($wgSharedDB). After it's completely installed, you can visit Special:SharedUserRights on your wiki and start adding new shared user rights to the database.

Download instructions

Installation
To install this extension, add the following near the bottom of the LocalSettings.php file of every wiki on your wiki family:

Next, run the queries in shared_user_groups.sql on your shared database, and you should be good to go.
