Announcing a new extension for USP Pro: Limit Posts Per User! This extension enables you to limit the number of posts that may be submitted by any user role(s). So you can limit registered subscribers to, say, 3 submitted posts, and limit authors to, say, 5 submitted posts. Plugin provides a settings page where you can customize your post limits as desired.
How it works
Install and activate the plugin. Visit the plugin settings page to set limits for any/all user roles. You can use
-1 for any user role to specify “no limit”, so users of that role can submit an unlimited number of posts. Here is a screenshot showing the options:
Note! You can view the number of posts that any user has submitted by visiting the User Profile screen.
