Need email notification of forum replies


I've been looking for a way to turn it on, but I don't see any option to get notified via email when someone replies to me in a post.  I don't even see a way to subscribe to an entire post, so that I get an email of replies there.

Am I missing something?  If it's not currently possible, is something like that at least planned?  With the volume that goes through these forums, it would be nice to be able to follow up on conversations without having to track down my posts and see if anyone has replied.
