How do I follow an important discussion?

Above each discussion or topic, there is a Subscribe toggle. Clicking on this will enable you to follow the discussion easier. Each time someone replies to the discussion, you will get a notification that will show on your Messages page. You can follow these notifications to the new content or delete them from the Notifications area on your Messages Page.

If you wish to no longer follow a discussion or topic, then clicking on the button again will turn off your subscription.
