I use a template to tell the user thankyou, and to give them a chance to print the information they just input on the form. If your form doesn't intake that much info, you might not need the template.
<input type="hidden" name="good_template" value="feedbackefile2.htm" />
you can try my form if you want it is not in production yet
you can view the source code if you like it. It is just a table with the same structure as the form.
right now I am working on getting the autorespond to work...it was working yesterday and now today...no...
