While you can subscribe to entire categories within Community and receive updates when newposts or comments are added to it, there are times when you’ll want to save the link to one particular thread; for example, a discussion post you find interesting, or an idea for a product improvement that you support.
To follow an individual post and receive updates when it’s commented on, you can bookmark it. Click on the bookmark ribbon when it’s available to add that item to your collection.
Your bookmarked items are always available from the right-hand sidebar when you are logged in. To remove an item from your bookmarks, simply click on the bookmark ribbon again.
