You have to edit index.php and online.php

Open index.php and find:
[php] if ($loggedin['usergroupid'] == 6 and $highlightadmin) {
$username = "<b><i>$loggedin[username]</i></b>";php]
and add below

PHP Code:

             } else if ($loggedin['usergroupid'] == XX and $highlightadmin) {
                $username = "<i><b>$loggedin[username]</b></i>"; 


Replace XX with the group id

find

PHP Code:

      if ($loggedin['usergroupid'] == 6 and $highlightadmin) {
        $username = "<b><i>$loggedin[username]</i></b>"; 


again and add below:

PHP Code:

             } else if ($loggedin['usergroupid'] == XX and $highlightadmin) {
                $username = "<i><b>$loggedin[username]</b></i>"; 


Replace XX with the group id

NOW open online.php and find:

PHP Code:

        if ($user['usergroupid'] == 6 and $highlightadmin) {
          $userinfo["$key"]['username'] = "<b><i>$user[username]</i></b>"; 


and add below

PHP Code:

        } else if ($user['usergroupid'] == XX and $highlightadmin) {
          $userinfo["$key"]['username'] = "<i><b>$user[username]</b></i>"; 


Now Modify the $username variable for each palce where it says XX to make whatever effect you wish for the username.

That should work, I havn't tested it.
