I'm trying to set up a glossary that allows me (teacher) to comment entries, but not the students. However, when I take away student permissions from "Create comment" (mod/glossary:comment), the students can't view comments, either. I make them (requests for edits to their glossary entries prior to my acceptance of them), but the students don't see them. The only way I can seem to get the students to be able to view comments is to give them permission to create comments.
I'd like to avoid this, because the more options my students are offered, the more creative ways they'll find to completely stuff the assignment up and then get indignant with me because Moodle isn't Snapchat.
