Formmail is a very easy to use form processor, simply place the following on any page after entering your domain. You can change this code to fit your specific needs.

<\FORM METHOD=POST ACTION="http://yourdomain.com/cgi-sys/FormMail.cgi"\>
<\input type=hidden name="recipient" value="sales@yourdomain.com"\>
<\input type=hidden name="subject" value="Order"\>
<\input type=hidden name="return_link_url" value="http://yourdomain.com/"\>
<\input type=hidden name="return_link_title" value="Back to MainPage"\>

Be sure to remove all of the back slashes (\) and replace yourdomain.com, with your real domain name.
