This plugin removes the ability for contributors to view or edit scheduled posts. It works by removing scheduled posts from the contributor’s list of posts in the posts admin list.

Restrict Contributors from Scheduled Posts

Restricts contributors from viewing or editing their posts after the posts are scheduled to publish.

List site contributors allows you list your site’s contributors and authors. 
Just add the shortcode [listsitecontributors] to a page on your blog. 
Optionally you can use the User Photo Plugin (https://wordpress.org/extend/plugins/user-photo/) for images, 
otherwise Avatars will be used.
