Not sure if this is already implemented and I just can't find it or what but it might be cool to have an option to follow a thread in the forums so that you get an email when there has been a new post to a topic. That way people don't have to find the thread that they have participated in and search for responses (if any), etc.
In fact I'd like to subscribe to this thread 
On the main forum page they do have a "See all my posts" tab right under the banner.
