Thats the point. We give them only a text area to add the mail addresses of the participants (comma separated).
"After signing up, the teacher and the student will see their own courses, not the others.
Set start page after login to Dashboard: Apperanace - Navigation Default home page"
I think they would still be able to show other user via Messages. Search for user or course displays all registered users, even suspended accounts. At least, I cannot find any way to limit results to "own courses".
Are you talking of this: Contacts tab in messaging provides list of all users (GDPR issue?) https://moodle.org/mod/forum/discuss.php?d=376212 ?
Yes! That's the one.
I remember voting for the issue in the tracker, but must have missed the update. So that should be solved any week now.
Great news, thanks a lot for the link.
