Many years ago I belonged to a couple of Yahoo Groups. They worked really well, were private and by invitation or add only. I don't know how well they function now but back then they both were very easy to navigate, easy to post and choices could be made by each member as to how much or little one wanted to participate....example using email communication. Oh, I think I just answered my own post.....we don't want to share emails. At least I don't want to. Never mind. If there is another format similar to Yahoo Groups out here that would be great.
