Thanks for that. The group I found is a closed one (and I have already been accepted). It was only when I got in there that I could see the members, with their alias and their real email, and I baulked! (They dont allow people to opt out totally of emails, and I understand that.)
My life is too complicated for more email addresses. My husband set his up to all arrive together in his in box but I just don't need the hassle- I cant even remember all the passwords I have already......
I prefer the way things work here I guess!
