Ok, here's how to get emailed replies to your post in this version:
When you make a post, you have the option of adding the thread to your "favorites". In "myHome" under the 3rd preferences item (which I believe is called subscriptions, email prefs, etc.) there is an option for having responses to all your favorite threads EMAILED to you. That's what I think you're looking for. This way, you can get email updates on a thread whether you've started it, responding to it, or just interested in the content.
