PHP Code:

        global $mod_cache;
        if(!$mod_cache[$post[userid]]) {
          if(ismoderator(0,"",$post[userid])) {
            eval("\$mod_cache[$post[userid]] = \"".gettemplate("moderator_icon")."\";");
          }
        }
        $mod_logo = $mod_cache[$post[userid]]; 


put that in functions.php above

PHP Code:

        // do posts from ignored users
        if (!$ignore[$post[userid]]) { 


create a template called
moderator_icon
--------------
<img src="http://yourforums.com/mod_icon.gif">

then in your postbit template put $mod_logo after the username in the postbit template
