If you have a discussion forum in Moodle you can choose to Subscribe or Unsubscribe to the forum. If you subscribe to a forum in Moodle you will not only see the post in the Moodle forum on your course page but you will also receive an email in your UofL email account to notify you that a new post was made in the forum. One exception is that if the instructor has chosen to make the forum a forced subscription you have no choice but to receive emails on every discussion posting.
To change your forum subscription settings:
Click on your profile, on the top right of your screen. Choose Preferences
From here you will see a list of preferences you can change. Choose Forum Preferences
Change your preferences to either subscribe automatically when you post to a forum or to not subscribe.
Remember to click Save the bottom of the page to save your changes.
