How do I get notifications for teacher comments on an unscored survey?

[jgalo]

I am currently trying to set up a class for my students and I want them each week to complete an unscored survey. I found it very easy to set up the survey, but my question is that I want them to be notified whenever I add a comment to one of their survey answers. There's a box to add the comment, but when I tested it out on a student account that I created, I couldn't figure out how to get notified that the teacher had made a comment. Any help would be appreciated. Thanks!
