When I am grading in Quizzes, there is a box below the student's response for the instructor to write an "additional comment".  I was so excited used it for the first time this semester because I appreciated the continuity of seeing my feedback directly attached to the specific question.  Unfortunately, it would appear that once the quiz is closed my students cannot see those specific comments.  I am wondering if there is a way to adjust the settings to allow them to see the comments I have made without giving them access to changing their answers by re-opening the quiz?  Or, do I only have the option to make comment in the right-hand column that they can view at any time?
