I want to create a group listing from existing emails w/o removing them from an existing TBird address book. I also don't want to reenter this data such as first and last names and their email addresses. I have multiple address books for Business contacts, Friends, Family, Neighbors, etc., and quite frequently a want to send a broadcast email to specific people within those groups, and other times I want to send another broadcast to other individuals. Basically, I want to setup Group A, Group B, Group C of addresses, where some people may exist in more than one group, as well as in their Friends, Family, Business, or Neighbors Mailing List.
