I will admit that I didn't know the functionality was available to email updates for subscribed forums (I knew it was for subscribed threads), has this been available for a long time?

Is there a way to change the settings for the forums I'm currently subscribed to so that it sends me emailed updates? I haven't been able to find a way to do this other than unsubscribing then subscribing again and turning on the email feature for each individual forum I want updates from.
