    I don't think www.shout.net uses e-mail. It appears to be a Web only
    interface. It also doesn't appear to use MIME.

    When I was using Netscape Messenger for e-mail I had the option to
    view messages by thread. It appears Netscape Messenger used two
    methods for finding a thread, Subject & Message-ID. Below is a list
    of headers from a Netscape message:
    Message-ID: <010401bf494e$e6d8ae20$47c5f5d1@biatch>
    From: "Michael @ MicroRationale" <michael@microrationale.com>
    To: <drobinso@nrg.com.au>
    References: <009501bf23bf$c5fbc340$53cc163f@biatch>
                        <381D3C67.3A306E6C@nrg.com.au>
                        <01fb01bf24b9$091cdf20$83cc163f@biatch>
                        <38214C52.35944612@nrg.com.au>
                        <004301bf26a4$999a9500$ed681b3f@biatch>
                        <3843329C.AA8B6835@nrg.com.au>
                        <003c01bf3bc8$90fa8b60$e1c2f5d1@biatch>

    The reference header appears to show past Message-IDs that I have
    sent to Michael. So Netscape could allow me to see those past
    messages if I haven't deleted them.

    But this only references the whole message not paragraphs that may
    have been quoted when replying. It would be nice if I could move my
    cursor over the paragraph that was quoted from a previous message I
    have sent and tell the e-mail client to open the message from my sent
    mail box and show me the complete message. For kicks it would be nice
    to have a check content option that would verify if the text quoted
    is the same text I sent and not modified in anyway.

    I don't know of anyone using MIME to create Content-IDs that allow
    the user to view/find the complete message the paragraph was cut from.
