Your email never appeared, which means that there's trouble on my end. A
more reliable email address was just emailed to your yahoo addy.
    usenet on my end is getting upgraded to provide functionality such
as UTF-8. My upgrade will include a proper usenet email address. Sorry
about the mixup.

Thank you,
