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:
Under the Settings Block, on the left of your screen. Choose Edit Profile.
From here, click on Preferences. You will now see the option to subscribe or unsubscribe to the forum discussion. If you choose Yes, you will receive emails when a posting is made.
Remember to click on Update Profile at the bottom of the page to save your changes.
