Hi,

I am going to have a stab at this based on some info gleaned from previous posts, because I don't have a copy of Mosets to test with directly.

$show = true; // sets as default, and we'll set to false if we are on a featured page
if (
  $option == 'com_mtree'
  and JRequest::getVar('task') == 'viewlink'
  and JRequest::getVar('format') == 'html'
) {
  $link_id = (int)JRequest::getVar('link_id');
  $db->setQuery( "SELECT link_featured  "
  . " FROM (#_" . "_mt_links)"
  . "\n WHERE link_published='1' AND link_approved > 0 AND link_id='".$link_id."' "
  . "\n LIMIT 1"
  );
  $result = $db->loadResult();
  if ($result) $show = false;
}
if ($show) return XXX;
// replace XXX with the module id of the module you want to show on all
// pages EXCEPT the featured item pages.


I hope that works and helps... please let me know if it causes an error or fails in any way. It might be quicker for me to log into your site and experiment with this to get it right, since I don't have mtree myself to test with.

Cheers,
Stephen
