Before you can receive notification e-mails for an active topic you must provide at least 1 verified e-mail address.

The system must make sure the e-mail address belongs to you in order to prevent misuse of that address. Once you have verified an email address there are 2 ways you can add a topic to your active topic notification list.

1) When creating a new topic or replying to an existing one you are given the choice to automatically turn on active topic notification. Select 'Yes' from the drop down menu.

2) When viewing a topic, you can click on the "Active Topic Notification" link located at the bottom right of each message in that topic.
