In admin/functions.php

Find:
====================
$post[message]=bbcodeparse($post[pagetext],$forum[forumid],$post[allowsmilie]);

//highlight words for search engine
====================

Replace with

if ($post[usergroupid]==6 OR $post[usergroupid]==5) {
$post[message]=bbcodeparse2($post[pagetext],1,1,1,1);
} else {
$post[message]=bbcodeparse($post[pagetext],$forum[forumid],$post[allowsmilie]);
}

//highlight words for search engine
===================

Just add more OR $post[usergroupid]==X to the IF statement for whatever usergroups you want to allow.

5 is Super Mod and 6 is Admin.
