I created a "What's New" control for Sitefinity that I'm sharing with everyone:http://www.goondocks.com/projects/goondocks-sitefinity-controls.aspx
This control simply returns links to the most recently updated pages in Sitefinity. You can chose the number of links that get returned.
Feel free to modify or use however you wish. If you notice any problems or discover better methods of doing something, please keep me in the loop.
