    Hi,

    I just fetched this via command line FTP (something's wrong with
    that URL in Bill's message below - perhaps underscores vs blanks)
    and converted it to PDF and posted it.

    Verified URLs are:

      ftp://ftp.pwg.org/pub/pwg/mfd/white/MFD_Outline_Nov_08.doc

      ftp://ftp.pwg.org/pub/pwg/mfd/white/MFD_Outline_Nov_08.pdf

    Cheers,
    - Ira
