Subject: Bugtraq Security Systems XMAS Advisory 0001

With interpretive art, the names are often just placeholders. Bugtraq
Security Systems requests that all the readers replace the names in this
advisory, including ours, with their own. Indeed, we exhort you to feel
that if you are not selling your integrity for stock options, not
pretending that each new bug found and fixed somehow makes the world a
better place, not sacrificing a sense of humor for a sense of importance,
that you are in fact, GOBBLES.

Yours Truly,
The Bugtraq Security Research Team
