So I graded an assignment using a rubric, but on some of the submissions I also sent a comment directing them to additional resources, explaining a particular point, etc.   Weeks later, my student says I never responded to her question that she asked about her grade. She also sent it as a comment on the assignment.  I never saw it until I went back to the Speed Grader, looked up her paper, and found it there.  Is there a notification setting that will signal me when students make comments on the assignments?
