There are a number of extensions and I saw another email mention them. However, I can't recommend strongly enough that you simply monitor the Recent Changes RSS feeds from your Wiki. If you have a few wikis, I would suggest setting up a planet feed of them. I use rawdog  to create a river of recent changes from about a dozen wikis I manage.
