Current admins of wiki's can see how the 3rd level will look on their current wiki if they edit their MediaWiki:Wiki-navigation and click on the "PREVIEW" button -- The Preview shows the new look with the "On this Wiki" tab - It is a fully functional preview - mousing over level 2 will show the level 3's if there are any.
