Actually, I always hesitate before calling myself an expert,
in spite of the credentials I have to back the title. Too
many people seem to think that if you disagree with their
point of view you can't know what you're talking about.

HeeHeeHee. Security questions are almost never true or false,
black or white, on or off. SPAM is *the* major computer security
issue and it has nothing at all to do with computers or security.
Is a use of strcpy() a security vulnerability? Sure it can be,
but in reality it almost never is, but the hysteria associated
with buffer overruns gave it a bad oder.

It's not so bad. We'll be OK. Really.
