In order to stay notified of recent posts on a forum, the Watch option is helpful.
Note: New post notifications will be sent to the user's external or Loyola email address, not via the Messages tool.
Go to Discussions.
Select Forums from the site Tool Menu.
Choose notification preference.
Select whether an email is desired for whenever a new message is posted on the Forum, for every new message posted on a conversation that the user has contributed to, or to simply turn off all notifications.
