This is untested, plus I'm going on 2.3.3 source, but it should be the same:

In newthread.php AND newreply.php -

Find:

PHP Code:

    if ($enablefloodcheck) {
      if ($bbuserinfo[userid]!=0 and time()-$bbuserinfo[lastpost]<=$floodchecktime and !ismoderator($foruminfo[forumid])) { 


Replace with:

PHP Code:

    if ($enablefloodcheck) {
      if ($bbuserinfo[userid]!=0 and time()-$bbuserinfo[lastpost]<=$floodchecktime and !ismoderator($foruminfo[forumid]) and $bbuserinfo[usergroupid]!=7) { 


** edited to reflect correct default vB USERGROUPID (7). Change if needed.
