ok, add a ne field to your thread table called acclevel, should be a small integer default 0

then edit postings.php:
section stick/unstick threads:

find

PHP Code:

if (!ismoderator($threadinfo[forumid],"canmanagethreads")) {
      show_nopermission();
  } 


below add:

PHP Code:

if($threadinfo[acclevel]==2 && $bbuserinfo[usergroupid]!=6) {
show_nopermission();
}
if($threadinfo[acclevel]==1 && ($bbuserinfo[usergroupid]!=6 && $bbuserinfo[usergroupid]!=5)) {
show_nopermission();
}

switch($bbuserinfo[usergroupid]) {
  case 5: $acclevel=1;
              break;
  case 6: $acclevel=2;
              break;
  default: $acclevel=0;

} 


then replace

PHP Code:

$DB_site->query("UPDATE thread SET sticky=$threadinfo[sticky],notes='".addslashes($threadinfo[notes])."' WHERE threadid='$threadid'"); 


with
[php]
$DB_site->query("UPDATE thread SET acclevel=$acclevel,sticky=$threadinfo[sticky],notes='".addslashes($threadinfo[notes])."' WHERE threadid='$threadid'");
