I believe you do use the sessions since there is a location row within it.

PHP Code:

  $datecut=time()-$cookietimeout;

  $loggedins=$DB_site->query_first("SELECT COUNT(*) AS sessions FROM session WHERE userid=0 AND lastactivity>$datecut AND location=$location");
  $numberguest=$loggedins['sessions']; 


you would want to work out the current location for the forums with this variabl.

$location

thats all I know about check for guests.
