Method to add user without using form POST?

I have a Contact page using form mail, and want to include a checkbox that enable visitors, to also subscribe to our Announce List when posting their form mail.

Is there a facility for adding users to the Announce List without using form POST?

Tried asking on the DH wiki but seems no one else is home :(

Also asked support, and they directed me here.

Right now our form & submit action processes the form mail, so thinking I could make some PHP call re-using the email address to subscribe to the Announce List somehow...

Help me jedis!! :P

Cheers, will give cURL a shot.
