I am just wondering how one would go about adding a Watch Forum and Unwatch Forum button (styled like the Sign up button) to a forum?
I have Social Groups by Waindigo installed, and this allows users to become members of the forum. However, I would like to replace this with a button that will make the member watch the forum. If they are watching the forum, it should display "Unwatch Forum" on the button. This uses the standard forum watch feature built into Xenforo.
