Dear Raymond, please do not blindly reply to some message when you want to create a new message. Despite editing the subject line the mail client sets some fields in the message header so that the message is displayed as a reply never the less and threading using those fields is messed up. Your method seems to result from using Web clients where it is not easy to just click on an address to compose a new one and to save oneself typing the address into the field. Since you are using Apple Mail you can just click an the ConTeXt email address in any message to compose a new message. Further tips on what to consider when dealing with lists are written down by openSUSE [1]. Thanks, Paul [1] http://en.opensuse.org/openSUSE:Mailing_list_netiquette
