If you are receiving new forum post email alerts from Moodle and would like for them to stop, you can “unsubscribe” from the forums. Note: in some cases, instructors “force” subscription so users have to receive email alerts.
To unsubscribe from a forum:
1. Click the title of the forum sending alerts (found in the subject line of the email)
2. In the left-hand settings block, click “Unsubscribe from this forum.”
That’s it! To subscribe to forums, click here
