All authors stats

Hi i was searching simple autors stats plugin to dashboard, but with no luck.
So i created dashboard widget:

// Author stats
	if ( is_blog_admin() ) {
		wp_add_dashboard_widget( 'dashboard_authorstats', __( 'Author stats' ), 'wp_dashboard_authorstats' );
	}

function wp_dashboard_authorstats( $args ) {
$allUsers = get_users('orderby=post_count&order=DESC');
$users = array();

// Remove subscribers from the list as they won't write any articles
foreach($allUsers as $currentUser)
{
	if(!in_array( 'subscriber', $currentUser->roles ))
	{
		$users[] = $currentUser;
	}
}

?>
<table>
<tr><td>
			<h3 class="authorName"><u>Author</u></h3>
		</td>
    <td width="20%">
			<h3 class="authorName"><u>Articles</u></h3>
		</td></tr>
    </table>
    <?php
foreach($users as $user)
{
$user_post_count = count_user_posts( $user->ID, 'post' );
	?>
	<div class="author">
		<!--<div class="authorAvatar"><?php //echo get_avatar( $user->user_email, '128' ); ?></div>-->
		<div class="authorInfo">
    <table width="100%">
    <tr><td>
			<h3 class="authorName"><?php echo $user->display_name; ?></h3>
		</td>
    <td width="30%">
			<h3 class="authorName"><?php echo $user_post_count; ?></h3>
		</td></tr>
    </table>
    </div>
	</div>
<?php
}

}

And now you can see authors list and number of posts for each author.
