I'm not sure if this is something you'd be interested in, but...We were using a list server created on our website previous to F1. Now we're in the process of switching over to just using F1 because we want to keep everything centralized (the boast of F1). We created an attribute grouping of E-newsletters and then have attributes such as Bulletin by email, News & Views (letter from the pastor), Men's Newsletter, etc. When someone wants to receive that e-newsletter, we assign them that attribute and create a people list via query builder and send out a group email (2.0 beta because it's the best). This works pretty well with the contact forms from Sunday mornings cards, as you can add attributes to the form and when checked it automatically assigns the attribute to that person. We haven't yet set up a way to sign up from our website (which I'm sure we will in the near future). We may just have an email sent to a specific person in the office and then they will assign the attribute to that person manually.
