List Post Authors Plus
List Authors Plus lets you list authors on your blog as well as filter out authors by role, individual ID or name. It’ll also organize the authors by most posts if you wish.

This plugin adds a new template tag, wp_list_authors_plus, which customizes and extends wp_list_authors. The new template tag can take all the parameters possible with wp_list_authors as well as the following new ones:

  • Excluded_ids – An array or comma delimited string of author ids to exclude from the list.
  • Excluded_usernames – An array or comma delimited string of author usernames to exclude from the list.
  • Excluded roles – An array or comma delimited string of roles to exclude from the list.
  • Order_by_posts – A value, either ASC or DESC, that indicates how to sort the authors by the number of posts they have. ASC causes the author with the leasts posts to be listed first, and DESC is the opposite.

It also adds an easy to configure widget for the sidebar that provides you with the opportunity to customize all the template tag’s parameters from one easy location for the widget that will be displayed.
