I would like to integrate MailChimp to more than 1 form of Quform. However, the MailChimp integration guide only shows how to integrate one form. The code on functions.php explains only how to integrate one form.
I have more than 5 forms I would like to integrate to the same MailChimp list. For example, I want the email fields iphorm_1_1, iphorm_2_1, iphorm_3_1, etc, to be integrated in the same MailChimp list. And I also want other name fields to be integrated in the same MailChimp list.
