I am running 1.6, but I cannot fix this problem.
I did login as a student then I went to my course to my edit profile, when I do that I can see the word "participant" on top, I click on it and I will have the list of all students for that course (or any other course) I am enrolled in.
****As an admin/teacher I do not want to allow students to see the participants on that course or neither to communicate with each others.
I went to variables / permission and I did setup showsiteparticipantslist: site teachers and then all teachers, but still not working.
Can you please help I don't want my students to see the particpants list, how can i do that?
