The Admin skin has been updated so that, if you choose, it can be used as the main skin for your portal.  The menu is horizontal and the left sidebar has been removed to allow for a much wider content area.  Need more space?  Use the Admin skin.  If you are using a logo, it will be inserted.  Don't have a logo, then choose "none specified" in the logo drop-down box in the Admin->Site Settings->Appearance section and it will automatically insert your website's title from the same page.  Your website's name will automatically be converted to a script font using a javascript font rendering engine.
