go obtain Dreamweaver MX, it uses full legit html and stuff. and if you really need to email someone make the script in PHP, from what i remeber (back when i attempted to learn PHP and failed
) it is just a call like 'email' or 'sendemail' and saving to a textfile is pretty easy.
$feedback = $_POST['nameoftextbox']
php.net can help aswell look for commands such as fopen fclose and fputs
