The name of this page is Example/HomePage. That is, this is the HomePage of a page-group named Example. Look just above the “Edit” tab - you can see the links “Example >> HomePage” which illustrate the group’s name is Example and the page’s name is HomePage.
A page-group (aka “wiki-group”) can be thought of as a mini-website. It will have its own group’s Example/RecentChanges page; it can have its own Example/GroupHeader, Example/GroupFooter and Example/SideMenu pages, and it can have any number of additional pages in the group - so, for instance, if this were the HomePage of a group devoted to an organization named “Example”, it might also make sense to have pages in the page-group named MeetingSchedule and MeetingAgendaMarch2007 and PublicEvents.
If there is also a page in the Main group with the same name as this group’s name — in this case a page named Main/Example — then a link from anywhere to
http://www.milwaukeerenaissance.com/Example will take the user to that page in the Main group. If that were to happen, it might be best to delete that Main/Example page from the Main group, so that a link to
http://www.milwaukeerenaissance.com/Example will bring the user to this - the HomePage of the Example group.
