How do I watch or subscribe to Discussions?
In order to stay notified of recent posts on a discussion, the Notifications option is helpful.
Note: New post notifications will be sent to the user's external/institutional email address, not via the Messages tool.
Go to Discussion.
Select the Discussions tool from the Tool Menu of your site.
Choose your notification preference.
Select whether an email is desired for whenever a new message is posted on the Discussion, for every new message posted on a conversation that the user has contributed to, or to simply turn off all notifications.
