Currently, users have no ability to delete or edit comments made on peer review assignments. This is a problem because students often assign a grade to their peer's work in the comments. This is a basic feature already implemented in discussions and feedback on assignments.
Testing has shown that the workaround defined below does not work.
The current workaround to remove an unwanted comment is for the TA/Instructor to:
- delete the person (who was being reviewed) and
- then re-assign them to the same reviewer.
- The student who did the review will then be prompted again to do the review
