I think you should comment the following in newreply.php

Line 104

PHP Code:

  // auto bypass queueing for admins/mods
  if (ismoderator($foruminfo[forumid])) {
    $visible=1;
  } 


Change to:

PHP Code:

  // auto bypass queueing for admins/mods
//  if (ismoderator($foruminfo[forumid])) {
//    $visible=1;
//  } 


If you want this only to one forum, then something like this will do the job:

PHP Code:

  // auto bypass queueing for admins/mods
  if (ismoderator($foruminfo[forumid]) && $forumid!=XX) {
    $visible=1;
  } 


And change XX to the forumid where the contest will took place.

Hope this helps.
