PHP Contact Form

Hi Everyone!

First of all, thanks for the awesome tutorial and forum space. Its really much appreciated.

I have a quick question for you all. I followed a tutorial for a PHP contact form posted here:

The question is, if I want this form to go to more than one e-mail address, what sort of code do I need to add into the PHP file?

Thanks so much!
