The Q&A forum - as per MoodleDocs - should work like this:
"In a Q and A forum, tutors post the question and students respond with possible answers. By default a Q and A forum requires students to post once before viewing other students' postings. After the initial posting, students can view and respond to others' postings. This feature allows equal initial posting opportunity among all students, thus encouraging original and independent thinking."
But how about if a student post once, read the others' posts than come back and "Edit" his post (he has 15 min to edit) or even worse, delete his post?
Is there a way in the Q&A to deny edit or delete for a student? Otherwise, i see this feature of hiding others' post as useless. Am i missing something in the Q&A forum?
I'm using 1.6.5
