Nate Baldwin also writes some really cool PHP scripts. A lot of people are using his NateMail script and the even more sophisticated commercial ProcessForm script. Both scripts are very secure and offer you a great variety of options...

Mindpalette GoLive actions

Nate Baldwin is my co-host at the Adobe user-to-user forum, and a graphic designer and PHP programmer. A very funny guy but deadly serious when it comes to GoLive actions. If you visits Nate's site you should definitely take a look at his fantastic NateMail PHP script. NateMail handles the form submissions on your site and the script is packed with useful features. NateMail comes in both a free and a commercial version, both are very easy to install! Web site: http://www.mindpalette.com Download page: http://www.mindpalette.com/actions/index.php
