When the admin/instructor creates a course, she gets the option to select whether she wants to enable feedback for that particular course.
He can opt to enable/disable or use the global setting set by the website administrator. Other than this, there is also a link to see all of the feedback submitted by users for that particular course.
The feedback is basically a personal message to the instructor regarding his/her course. As such it is only available in the WordPress backend and isn’t shown on the frontend of the website. So there is no need for approval/rejection system for feedback messages.
