There is a feature to "subscribe" to the posts or threads that interest you. When you start a topic, or reply to a topic, type in the information that you want in your post. Then before you hit the "post" button, look below the input box to the "Attachments and other options". Click on that button just like if you wanted to post a picture. Once it opens up, there are several small boxes that you can select. Click on the box that has "Notify me of replies" next to it. Now you should receive an e-mail whenever there is a new post to that topic.
I believe that there is also a feature in your personal user control panel you can select, that automatically subscribes you to every post that you make.
Good luck
