Hi,
We are using Membership Pro to manage membership subscriptions (enrollment and profile updates) and Community Builder for user lists. We'd like to integrate a MailChimp-based newsletter for our active members with an opt-in at membership creation. Do you have a plugin so that an opt-in into the mailing list is visible when the user creates a subscription using Membership Pro?

Alternatively, we pass a number of custom fields along to Community Builder for use within CB. Will passing this field to CB allow the communication through CMC to add the user to the mailing list?

Thanks in advance for your feedback, trying to figure this puzzle out.
