intact so that people (like me, who sort the mails in threaded fashion using the Subject line) may keep track and enjoy the discussion.
But, that is a very bad way to sort mails. The proper way is to use the X-BeenThere header for mailman mailing lists. Other mailing list software have their own way of allowing a recipient to distinguish between diffirent copies of same mail, one coming as a personal cc; and another coming via the mailing list.
Your subject line ofcourse relates to your content, but It would be a good ( list) practise I believe. What do you say?
If you use the X-Beenthere header, even if you change the subject line, the mail will continue to be threaded in good mail user agents / clients.
