Can someone summarize the ramifications of tweaking the subject line in a post? Assume: Some-original-subject Normal reply yields: Re: Some-original-subject If a reply is made and the subject line is (mistake, whatever) trashed, then manually re-inserted, does re: Some-original-subject (change in case of Re) preserve threading? Does change in case of words in subject line preserve threading? More generally, what permutations of the original text still preserve threading -- addition/deletion of various kinds of white-space, etc. Is threading solely in the domain of the mail reader, or is there something in the header besides the text of the header itself that aids threading? If a subject digresses and one changes the subject line to Re: New-subject (was: Some-original-subject) is threading preserved? Thanks, Gary
