I have a course with some 5000 students in it and 180 teachers. It has about 700 different groups in it. I have a forum which I have set as separate groups, and grouping with the only group in the grouping being the teachers' group. I have also tried this with "no groups" and "restrict access" set to group "teachers". I have the forum hidden to everyone but teachers. I really want all teachers, and only teachers, to receive email notifications when someone posts to the forum. When I set the forum to "forced subscription" I can see in the "who is subscribed" list, all of the teachers yet no email notifications go out. When I set it to auto-subscribe it tells me "everyone is subscribed" but when I look at the list of those subscribed it is empty. When I post, I get an email as does anyone subscribed to that thread but not the whole forum. In past versions of Moodle in the same setting, mail went out. I'm now using Moodle 3.8.2
Is this a bug or am I doing something wrong? I have tried to search for similar problems but to no avail. If anyone has any ideas I'd be most grateful to hear them.
