If you find an interesting forum discussion you’d like to keep track of, you can use the built-in feature to follow it. When you follow a discussion, you’ll receive an email whenever there is a new reply to the discussion. This email notification will contain a link to the new reply.
By default, you’ll automatically follow all discussions you start or reply to. This is a great way to stay on top of the discussion and make sure you see all replies.
To follow a discussion, go to the page for that discussion and click the link to “Follow – Email me when people reply.” If you’re already following a discussion and would like to stop doing so, this link will appear as “Stop Following”. Clicking that link will stop email notifications about new replies to the discussion.
