The widget acts like any other Apple Dashboard widget. You can activate it and move it to any portion of your screen. Utilizing RSS, the widget will check the louisgray.com site every 15 minutes for new posts, and will display their headline and date in the widget, so you can see if the site has been updated, and click directly to the post. In fact, the 1.0 version of the widget has all posts available from the site, going back to the beginning of the year!
