Extension:MarketResearch

<?php /**

* CategoryWatch extension
*
* 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.
* 
* In addition to the normal behaviour, this extension sends a message to the users
* watching category pages when membership changes listing the articles which were
* added and/or removed from the category.
*
* See http://www.mediawiki.org/Extension:CategoryWatch for installation and usage details
* See http://www.organicdesign.co.nz/Extension:CategoryWatch for development notes and disucssion
* Version 0.0.1 started 2008-07-11
* 
* @package MediaWiki
* @subpackage Extensions
