Adding an icon beside the usernames of certain usergroups

First off, 1.4 is rockin'. Thanks for all the hard work.

I'd like to do what the title says. I found a couple mods on punres along the same lines (http://www.punres.org/files.php?pid=56 and http://www.punres.org/files.php?pid=445) and managed to sort of get something working.

Basically just editing viewtopic.php, replacing:

<dt><strong><?php echo $username ?></strong></dt>

with

<?php
if ($user_title == $lang_common['Administrator']) {
        ?><dt><strong class="admicon"><?php echo $username ?></strong></dt><?php 
}
elseif ($user_title == $lang_common['Moderator']) {
        ?><dt><strong class="modicon"><?php echo $username ?></strong></dt><?php
}
else { ?><dt><strong><?php echo $username ?></strong></dt><?php }
?>

This of course only works when the the users title is either 'Administrator' or 'Moderator'.

I tried to figure it out from examples in existing files but my php is super weak.

Something with these?

($pun_user['g_id'] == PUN_ADMIN

($pun_user['g_moderator'] == '1'

Thanks for any ideas.
