title: Possible to provide a subscriber's language through MailChimp API?
body: <p>Currently, I have a signup form on a PHP page, which allows a user to enter their name and email address. </p>
  
  <p>When pressed, it fires an AJAX POST to the server, and the PHP script which receives the postdata takes it and uses the MailChimp PHP API to sign up the user (via listSubscribe()).</p>
  
  <p>It's a multilingual site and the issue with this is that MailChimp has no idea what the user's language is when the signup is performed via an API call. This means that the user receives their MailChimp confirmation email (i.e. 'did you actually sign up for this' etc) in English, regardless of their actual language preference.</p>
  
  <p>The way I've worked around this at the moment is to create separate lists for each language, subscribing the user to the appropriate list based on which language they're viewing the site in. This means that you can set the MailChimp forms default language to the language of the list.</p>
  
  <p>This feels very hacky to me, is there a better way? Doing it this way means that campaigns must be set up for each language etc.</p>
