If you click on Thread Tools on the right hand side, above the first post, you will see several options in a popup box. Click on Subscribe to this Thread. Then you will be taken to a page where you can choose which kind notification you want by clicking on Notification Type. I choose Instant email Notification for the few threads that I follow. Be sure to click on Add Subscription after you have made your choice. You can also place the URL in a folder, but I prefer the notification by email.
