Announce List using PHP

I’m trying to setup a subscription form within flash for the standard Dreamhost announce lists using php. I believe I have the flash side covered but am unsure as how to setup the php.
any help would be greatly appreciated.

Yeah, I’ve seen that. I’m not terribly familiar with PHP but isn’t that just standard HTML (and for e-mail)? How do you add that form to a PHP script (triggered by flash) that acts to subscribe users to the announce lists?

thank you!
