How do I follow a topic on IMWA forum?

Hi Chris
I was wondering if there is a way on the IMWA forum that a person can follow a certain topic and then get an email update when the topic is updated.. i.e.
1. you post a topic
2. you indicate that you want to follow this topic
3. when a person replies to the topic you either get an email notification or an email containing the reply.
Would be useful.
