Adds a checkbox to site-wide contact forms allowing users to subscribe to your newsletter while contacting you.
The module notifies the administrator and includes the subscribe email address in the contact message.
It can also interact with a newsletter management system like Campaign Monitor (other systems can be added in one function).
Drupal 4.7 version now available via CVS. It's almost the same code as for Drupal 5.0
Future versions will include a settings page and support for more newsletter management applications.
