   I'm looking for a widget that specifically lists members with certain capabilities. I have a client that wants to have a widget that lists the contributors on his site separately from other authors. Is there such a widget? If not, I think I will have to either make a little "fake" author widget and code it manually, or else alter the WP-Authors widget with a customized version of wp_list_authors().

   Thanks,
   Frank

   I wound up replacing the wp_list_authors() function. It went pretty smoothly. Here's the function I made (sorry, it's long):

   function custom_list_authors_2($args = '', $user_levels) {
   	global $wpdb;
   
   	$defaults = array(
   		'optioncount' => false, 'exclude_admin' => true,
   		'show_fullname' => false, 'hide_empty' => false,
   		'feed' => '', 'feed_image' => '', 'feed_type' => '', 'echo' => true,
   		'style' => 'list', 'html' => true
   	);
   
   	$r = wp_parse_args( $args, $defaults );
   	extract($r, EXTR_SKIP);
   	$return = '';
   
   	$user_levels = implode(',', $user_levels);
   	$contributors = $wpdb->get_results("SELECT user_id from $wpdb->usermeta WHERE meta_key = 'wp_user_level' AND meta_value IN ($user_levels)" . ($exclude_admin ? " AND user_login <> 'admin' " : '') );
   
   	$contributor_IDs = array();
   	foreach ( (array) $contributors as $contributor )
   	{
   		$contributor_IDs[] = $contributor->user_id;
   	}
   
   	$contributor_IDs = implode(',', $contributor_IDs);
   
   	/** @todo Move select to get_authors(). */
   	$authors = $wpdb->get_results("SELECT ID, user_nicename from $wpdb->users WHERE ID IN ($contributor_IDs)" . ($exclude_admin ? " AND user_login <> 'admin' " : '') . "ORDER BY display_name");
   
   	$author_count = array();
   	foreach ((array) $wpdb->get_results("SELECT DISTINCT post_author, COUNT(ID) AS count FROM $wpdb->posts WHERE post_type = 'post' AND " . get_private_posts_cap_sql( 'post' ) . " GROUP BY post_author") as $row) {
   		$author_count[$row->post_author] = $row->count;
   	}
   
   	foreach ( (array) $authors as $author ) {
   
   		$link = '';
   
   		$author = get_userdata( $author->ID );
   		$posts = (isset($author_count[$author->ID])) ? $author_count[$author->ID] : 0;
   		$name = $author->display_name;
   
   		if ( $show_fullname && ($author->first_name != '' && $author->last_name != '') )
   			$name = "$author->first_name $author->last_name";
   
   		if( !$html ) {
   			if ( $posts == 0 ) {
   				if ( ! $hide_empty )
   					$return .= $name . ', ';
   			} else
   				$return .= $name . ', ';
   
   			// No need to go further to process HTML.
   			continue;
   		}
   
   		if ( !($posts == 0 && $hide_empty) && 'list' == $style )
   			$return .= '<li>';
   		if ( $posts == 0 ) {
   			if ( ! $hide_empty )
   				$link = $name;
   		} else {
   			$link = '<a href="' . get_author_posts_url($author->ID, $author->user_nicename) . '" title="' . sprintf(__("Posts by %s"), esc_attr($author->display_name)) . '">' . $name . '</a>';
   
   			if ( (! empty($feed_image)) || (! empty($feed)) ) {
   				$link .= ' ';
   				if (empty($feed_image))
   					$link .= '(';
   				$link .= '<a href="' . get_author_feed_link($author->ID) . '"';
   
   				if ( !empty($feed) ) {
   					$title = ' title="' . $feed . '"';
   					$alt = ' alt="' . $feed . '"';
   					$name = $feed;
   					$link .= $title;
   				}
   
   				$link .= '>';
   
   				if ( !empty($feed_image) )
   					$link .= "<img src=\"$feed_image\" style=\"border: none;\"$alt$title" . ' />';
   				else
   					$link .= $name;
   
   				$link .= '</a>';
   
   				if ( empty($feed_image) )
   					$link .= ')';
   			}
   
   			if ( $optioncount )
   				$link .= ' ('. $posts . ')';
   
   		}
   
   		if ( !($posts == 0 && $hide_empty) && 'list' == $style )
   			$return .= $link . '</li>';
   		else if ( ! $hide_empty )
   			$return .= $link . ', ';
   	}
   
   	$return = trim($return, ', ');
   
   	if ( ! $echo )
   		return $return;
   	echo $return;
   }

   Stick this code at the top of your file and call it in place of wp_list_authors(). The added parameter is an array of user levels to select for. 10 = admin, 7 = editor, 2 author, 1 = contributor. The query probably could have been done better, but it saved me lot of time in writing it. Hopefully, somebody will find this useful.

   I am curious how you got this work. I have added this into my functions, but it returns no results.
