Well, darn, Joseph. How lucky we've been, considering the "lack of security"
on our system. In all the time it's run, we've had no problems, attacks,
down-time, viruses, trojan horses, or anything else, for several years now.
Thanks for making me feel so lucky!
Of course, there's always the possibility that we ARE security experts, but
thankfully, you have made us realize that it's all been pure luck. I guess
I'll just have to take the MCAD course to become one.
