Thanks for the moral support. Message origin is subtle business. In addition to "Sender" which is used by mailing lists and other proxy agents, there is also "Resent-From" and friends. I am rather partial to "forwarding" messages not in-line or as attachments, but as "resent" messages. MUAs should expose message origin when different from author. > FWIW, the text is from the proposed charter, I didn't write any of it. Yes, of course. -- Viktor.
