A way around this might be to flag namepages as somehow "different" and exclude them from the listing, for example by excluding pages that link to CategoryHomePage, or that just link to it at the end of the page. An alternative is to exclude forward links that are preceeded by a double-hyphen ala "--" as common convention is to sign "-- MyName".
