List Authors Including Admin

Hello.

I’m using this code to display a list of all authors on my blog; however, I’m running into two problems. First off, it is only displaying my two authors but I’d like to display myself (admin). How can I do that?

Also, how can I display each post count associated with the author and admin next to their name?

<li class="widget widget_authors">
    <h2><span>Authors</span><small></small></h2>
    <ul>
    <?php wp_list_authors('show_fullname=1'); ?>
    </ul>
</li>
