Stacy Horn and the good folks of the Heart of ECHO suffer me to me run
the free user mailing lists on Echo, so if you've got questions about them
just give me a yell at listproc-manager@echonyc.com.
Note well: the listproc mailing lists I administer do not provide commercial-grade
service, but you can't beat the price.
Used to work at a place called Rabbit Software. If by some intensely weird
happenstance you happen to have had some affiliation with that fine outfit,
drop me a note and I'll clue you
in to where the ex-Rabbits hang out.
