1. Allow user rating for every activity.  so that the teacher may know which activity is most useful for students and which is less helpful. 

2. Provide option to report activity to admin on scales like inaccurate, vulgar post etc.

admin,teacher will able to track highly rated posts, pages using a dashboard. it will also increase user interaction. based on rating we can define popular posts , or pages through block.

this feature would be a nice addition to the moodle.
