In the 'More Actions' tab, which is visible to the owner or collaborators of a particular page, you can change the 'properties' of the page.  You can subscribe to the page settings, change the page settings, print the page, move the page to another place in the site, delete the page, share the site with others, or view the site map.  There is also an 'Advanced Settings' link at the bottom, which allows you to make the site globally significant.
