shouldn't be a problem too
open showgroups.php
line 175:
while ($user = $DB_site->fetch_array($users)) {
below add: $user[username]="<font color=red>".$username."</font>";
this are the moderators
line 108:
if ($usergroupid == 6) { // Admins
below add: $user[username]="<font color=red>".$username."</font>";
this is for the admins
then find
} else if ($usergroupid == 5) { // Super Mods
below add: $user[username]="<font color=blue>".$username."</font>";
this for supermods.
not tested but should work
