Every page (apart from the home page) has navigation links just below the top banner. If you click the far right link on a given page, that page will be added to your personal bookmarks, which will be displayed on the site home page.
If you have at least one personal bookmark then the bookmarks for unregistered users (currently this Message Board and the Latest Prog) will not be displayed.
You can remove bookmarks by clicking the remove link on the home page.
