How do I watch or subscribe to forums?
The Watch option notifies you of recent posts on Discussions.
Note: New post notifications will be sent to your email address, not via the Messages tool.
Go to Discussions.
Select Discussions from the Tool Menu in your site.
Select the Watch tab.
Choose your notification preference.
Select whether to receive email for every new message posted on the forums or every new message posted on a conversation to which you have contributed, or to turn off all notifications. The default is to receive No notification.
