There are two customizations you can add to the cgiemail script. 
One customization is a success page so that when folks fill out 
your form and hit submit they get a different page, rather than 
the one that lists the results they posted. You would do that with : 

<INPUT TYPE="hidden" NAME="success" VALUE="http://www.domain.com/page.html"> 

There is also a failure page for when someone doesn't fill out a required field : 

<INPUT TYPE="hidden" NAME="failure" VALUE="http://www.domain.com/failure.html">
