How do I subscribe to a subforum?

In Xenforo Forums, there's a feature where the user can subscribe only to a certain subforum. I believed this forum is using, or is powered by, Xenforo Forums.

So, how do I subscribe only to 1 subforum, so I only get all sorts of alerts only from that subforum?

If possible, how do I subscribe to multiple subforums, with the same behavior as mentioned above?

 

When you're in the subforum, there's a button to the top right, just over the last message column, that says "watch forum".

 

Thanks, @Baste! You should be able to watch as many forums as you like with the "Watch Forum" button.

 

Thanks.
