A small but mighty new feature allows project managers to a their own custom link to the public project dashboard.  The link could take users to a custom project website, a Facebook page, a Flicker slideshow or any other web-excessible resource.

To add a custom link to your public project dashboard, enter the link via the project settings page in the projects portal, as illustrated in the image below.

Once that is done, a new menu item will be available in the 'more data' tab on the project dashboard.  The new "more about this project" item will be a link to your own custom web presence for the project.
