eNewsletter - Groups & Subscription Lists

Hi there,

I was wondering how the eNewsletter plugin works with individual events. The users who registered were not part of any of the 'member groups' I created. I had to go in and manually edit where they all went/go in order to send out a test eNewsletter.

What I'm wondering now is - do I have to do this each time a user RSVP's for an event or are they added to the event/group? I'm not seeing how it is supposed to work and a little confused.

Thank you for the help/clarity.

Bryan
