Well here you go!
Find this line in profile.php first:
PHP Code:
$article_content .= "<li><strong><u>{$lang_basic_info} {$user}</u></strong><br /><br />
<img src='{$row->avatar}' border=0 width='100' height=100 /><br />
<strong>Member Since:</strong> {$row->membersince}<br /><br />
Gender: {$row->gender}<br />
Favorite Color: {$row->color}<br />
Nickname: {$row->nickname}<br />
Bio: <br />
{$row->bio}<br /></li>";
And replace with:
PHP Code:
$usergroup = $adopts->join("groups", "groups.gid = users.usergroup")
->select("users", array(), constant("PREFIX")."users.username = '{$user}'")->fetchObject();
$article_content .= "<li><strong><u>{$lang_basic_info} {$user}</u></strong><br /><br />
Usergroup: {$usergroup->groupname}<br />
<img src='{$row->avatar}' border=0 width='100' height=100 /><br />
<strong>Member Since:</strong> {$row->membersince}<br /><br />
Gender: {$row->gender}<br />
Favorite Color: {$row->color}<br />
Nickname: {$row->nickname}<br />
Bio: <br />
{$row->bio}<br /></li>";
