FWIW, reply and reply all in Gmail web interface now lists both addresses (originator and mailing list). I don't know if this is a change again.
Also, I find it somewhat funny in a bizarre way that people on this list who have experience with all kinds of systems, all kinds of user interfaces and many generations of machines (computers and otherwise) can complain over a little thing like this change. (Bikeshed?) Funny, now I suddenly feel a lot older than my fifty one years. HAND, -- Regards, Torfinn Ingolfsen
