I forgot to mention the forum's subscription system. By default, the forum sets your subscription preference to no email. When you create or reply to a thread, the forum will track your interest in the thread and you can monitor when your subscribed threads have replies easily by checking you control panel (see "User CP" link at the top of the page).
You can change your subscription preference from your control panel (see edit options in the left hand menu on the control panel page) to send you email alerts if you like.
