Riz,
Best thing to do imo is to select "Thread Tools" -->> "Subscribe to this Thread" and you will have various options to choose from, including "instant email notification". When a new post is added to a particular thread you will receive an e-mail to alert you. It works very well and you can select many threads that interest you.
You can then view your "subscribed threads" under your User Control Panel.
Hope this helps
