That's correct. Page Display Options has 'Show Page Heading' > No. But this 'Home' text was here before I even created any articles. There are no articles named 'Home'.
Internet Explorer lists it as part of a div called rt-pagetitle. If you open the URL in IE and click F12, then using the selection pointer from the tools... then select the box that is just for the text 'Home', you'll see what I am referring to. Maybe this should be changed somewhere in the CSS.
