Thread:Project:Support desk/E-mail notification

Hi I've just been asked to look after a mediawiki and of course now people want more from it. Is there an extension or some other method such that users can be notified by either RSS or e-mail of "quote" when someone adds a file or contributes to the discussions "end_quote"? We are using:

Product	Version MediaWiki	1.18.2 PHP	5.3.10 (apache2handler) MySQL	5.5.21

TIA Paul
