I have a simple member subscription form on a site and would like to somehow make it not only subscribe users to the site but also add their email to my mailchimp list. So, basically my form has its "action" now and I have another action URL for mailchimp with my ID and all. I was wondering if it is possible that when user clicks on submit button they become a member (form makes the action 1) and at the same time their email forwards to mailchimp list (transfering the value from only that input field to action 2).
