wrong again.


I find it truly amazing that so many people that spend so much time
doing stuff have no idea how it works! I guess the hackers should
be very happy that they've made the process so transparent that you
(apparently) don't have to know how it works to make it work. Good
job guys.

I'm tired of getting flamed when I'm right...this is almost as bad as
the bsd/os list!
