At the top of each forum thread, on the right, just above the top post, you will see this:
[Previous Thread | Next Thread | Subscribe to this thread | Show Newest Post First]
If you click on the "Subscribe to this thread", you will get one email notification of a new post - but only when the first person to respond posts. If you don't follow the link included in the email, you won't get another email notification.
I just make sure I follow the link in every email notification that I get so that I continue to get them.
To unsubscribe from individual threads, go to the My Profile --> Edit Email Subscriptions tab to remove your email notification subscriptions.
Oh, and you have to have your email enabled on the forum, I believe.
