Well, currently, I just look up a PTV in the groups GroupHeader page and use
it if it exists, or I just return the group name as the home name. My function is:

function HomePage($group)
  { global $DefaultGroup;

    if( !$group ) $group = $DefaultGroup;
    $gh=MakePageName($group,"GroupHeader");
    $home = PageTextVar($gh,'HomePage');
    if( !$home ) $home = $group;
    return $home;
   }


The trouble is, I'd rather not have to hunt for all occurrences of [[Group/]]
in my wiki and replace them with [[Group/{Group.$HomePage}]] or something...
