Thanks, @donavonguyot and @wysija, for putting the 3.0 version together!
I’m wondering if anyone can answer a support-type question related to this plug-in. I’m setting up a registration form where a user can select to which lists to subscribe (e.g. All, News Only, Events Only, Announcements Only). I’m probably doing this wrong but I’ve setting up a feed for each checkbox mapped to the MailPoet list. It seems like if a user selects the first box, it doesn’t process the additional boxes, which means they are not subscribed to the lists they selected, only the first one. Is there a trick to overcome this?
