Wiki RSS Feeds
Good news. It turns out you can get a RSS feed for your wiki pages. I learned this by linking through a web page I was reading for Digital History, called "Introducing MediaCommons," by Kathleen Fitzpatrick.
In order to receive an RSS feed for a wiki, you simply need to go to the article's history page and look at the left-hand column under the toolbox (I should note that this is almost verbatim from the page on which I discovered it. You can read that article, if you like).
For those of us in the Public History class working on our wiki, it will help notify us of changes. And for those of us in Digital History who created or made changes to a wiki, it may also prove beneficial.
