In the far right on a CodePlex project is the RSS button.
When you click on the RSS link or button, you’ll see a list of RSS feeds to choose from.
All Project Updates will show you all activity on the site, from source code check-ins to updates to work items, and everything else in between.
For example, here’s the RSS feed for everything related to xUnit: http://xunit.codeplex.com/Project/ProjectRss.aspx
