Do you mean "get an email" when someone replies to your thread?

There are two ways to do this.
1. When you preview the thread (before posting it), there is an option to set the thread subscription.

2. At the bottom of every thread, there is also a "subscribe to this thread" link as well, so you can watch interesting threads even if you didn't start them.
