Yes, I only requested that people not change the subject headers for trivial reasons, by which I meant things like fixing typos (as in the subject header change that brought about this thread). I also only intended my request in the context of this forum, which is shared between Usenet and mailing list users. Changing the subject header to indicate a change in subject is, of course, fine. -- https://mail.python.org/mailman/listinfo/python-list
