Extension:CategoryWatch

A feature that's missing from the MediaWiki Watchlist functionality is that if you watch a category page, you will only be notified when the content of the category page text changes. You won't be notified when pages are added to or removed from that category though which is probably the main information you were wanting when deciding to watch a category page.

This extension was developed primarily to be used in conjunction with the Workflow extension, but it can also be used by itself. When used with the workflow extension, it allows roles to be notified when work items have changed state and been moved into a category they're responsible for.

Installation
Note that this extension currently requires the MediaWiki to be of at least version 1.11. Create a CategoryWatch folder in your extensions directory. Download the latest snapshot and extract it to your extensions directory. Then include it in your LocalSettings.php file as in the following example.

Configuration
One global variable called $wgCategoryWatchNotifyEditor can be set to true which will allow the user who re-categroises an article to also receive the notification message if it is a category they are watching. This is useful so that the editor has an audit trail of all membership changes to categories they're watching.
