I do not want to build a thread, so kindly do not respond on- (or for that
matter, off-list).

If (as one member mentioned) the link doesn't work, take a few extra
seconds and go to http://www.arin.net/mailing_lists/index.html and follow
the idiot-proof instructions, and spare the rest of us the inconvenience
of reading your misdirected messages.

sheesh.
