Thanks, I found it. Unfortunately it isn’t working. I double checked the Mailchip API code and also the List ID code in the Mailchimp subscribe field. They look both correct. Nothing is added to the list nor do I receive an e-mail for confirmation (although I hope it isn’t a double opt-in construction, since they are registering already on the site). Please advise what to do now.
Sorry. Account has been verified now.
