So I've got a bi-lingual site using WPML and I'm using Gravity Forms with the Mailchimp add on to create signup forms. I've created two groups in Mailchimp for preferred language and I was wondering if there was a way to populate a hidden field in gravity forms to pass the language set in the website to mailchimp to sort the signup into the appropriate language group.
The site is http://www.thegreatrideofchina.com
Thanks!
