How to "Follow" a post

Below every forum post is a rectangular button with a circle in it - Click it to see different options for notifications to this post.


There may also be a circle button on the right side if there are a number of replies to the post.


If you click “Watching” you’ll be notified when anyone replies, but without having to add a “Following” reply of your own (like in G+), which would clutter the original post.
