Hi everyone, I know in a course like this notifications can become a bit cumbersome. There is a profile preference in Moodle that allows you to receive one email per day with all the forum activity - instead of one email every time someone posts. To change the preference click on your profile picture on the top right (next to your name) and select preferences. Then under user account choose forum preferences. Under email digest type make your choice (complete or subjects). I also like the highlight feature under forum tracking but that is up to you. Save changes.
Here is a quick screencast of these directions as well.
Keep up the participation - it is awesome!
