My son is at UCL. When he was home recently, and using his university email account, I noticed it was full of unread Moodle forum messages. I asked him what they were and he said he gets an email every time someone posts in one of the course-related Moodle forums he is subscribed to. He showed me some and a lot of them were questions from other students about assignments, with answers from the course tutor, so not directly relevant to him. I asked him why he didn't unsubscribe from the emails and he said that was because occasionally there is something important, though he didn't explain how he would recognise that from an unopened email when they all seem to have the same subject line (something like 'message from UCL moodle forum x'). I left it there, but I'm wondering if all student email inboxes are similarly clogged. Surely it can't be the default?
