Email form with 2 posts actions?

[sKunKbad]

I have an email form, and users can select to be added to our email list with a radio button, which is mailed to me in the body of an email. On a seperate page of my website there is a form where users can sign up for this email, and that form sends the data to en email administration program that is seperate from the email processing script. Is it possible to have a form that posts to both the email processings script certain data, and posts other data to the email processings script?
