Hey,
This plugin seems great. It's exactly what we've been hoping to find and add to our organization's blog.
But the newsletter we're hoping to promote is not being shown on the drop down menu with our several Mailchimp lists. There have been too many others created since the one we hope to promote (all of which we still use). So simply put, we don't have the option to add the newsletter that we want right now.
I'm wondering if there is a simple solution or if this comes down to making adjustments within MailChimp?
