Matt, thanks! this was so clear & helpful. I do have one question. Is there a way to remove the Subject and message field? so:
if your subject line just says: Sign up for future updates, and you don't want anything but their email address for your update list - the user doesn't see anything but the subject line and Name & E-mail fields?
<h4 class="widget-title">signup for future updates</h4>
