[Mediawiki-l] IM/Mobile/Email Notification extension

[Eric K]

I have to keep checking Recent Changes for my wiki to catch vandalism as it happens. Is there an extention that would send an alert on my IM, cell phone or send me an email when an edit happens?
I guess I could edit my current extension to include the email feature but I was wondering if anyone already has such a notification extension with better features that I could make use of.
 
thanks!
Eric
