    <?php $usernames = $wpdb->get_results("SELECT user_nicename, user_url FROM $wpdb->users ORDER BY ID DESC LIMIT 5");
        foreach ($usernames as $username) {
                echo '<li>' .get_avatar($username->comment_author_email, 45).'<a href="'.$username->user_url.'">'.$username->user_nicename."</a></li>";
        }
    ?>
</ul>

<?php $usernames = $wpdb->get_results("SELECT user_nicename, user_url FROM $wpdb->users ORDER BY ID DESC LIMIT 5");
