I am trying to figure that out myself and will report back once I have. So far it seems if you subscribe to an individual thread, you will see those subscriptions in your subscription folder. Also, you can go to your profile page (just click on your name to go there) and click the "subscriptions" tab. But you manage subscriptions from the settings>> subscriptions area. (YOu can even create different folders to organize your subscribed threads). But as for subscribing to an entire forum, if you select to be notified by email, it will send you an email when a NEW thread is posted (not for every reply/post or your inbox would fill up fast). But why the forum subscriptions don't show up in the subscriptions folder, I'm still trying to find an answer.
