The MailChimp plugin works great for me. It does a great job of populating the members First Name, Last Name and Email address. I want to capture more info into MailChimp including Address, City, State, Zip and Phone. I have the fields created in my MailChimp list and in aMember's signup form but they do not populate from aMember to MailChimp. I suspect the field names at MailChimp must have very specific names. How is this done?
