Contact at Applied Theory?

Hi.

Can anyone point me in the direction of the email address of a clueful
person at Applied Theory? I've emailed the address at
http://puck.nether.net/netops/nocs.cgi nearly 24 hours ago, but gotten no
response, and I'm getting slightly tired of any packets from here to
EarthLink disappearing into some equivalent of Null0 or /dev/null somewhere
on Applied Theory's network.

TIA,

Vivien
