If some people don't know the correct terminology then they should be
taught the correct terminology immediately, if not before and sooner than
that if possible. Because of one person who spelled a word incorrectly in
the subject line we have hundreds of subscribers seeing that incorrect
spelling over and over and thinking that's the way it should be. Shame on
anybody who allows something like that to slide. What's more important,
sparing the feelings of a numbskull or demonstrating correct terminology
to the maundering masses?

Why is it, then, that you failed to follow your own stated philosophy? You
offered NO correction, but only propagated the error.

BTW, why do you choose to propagate a misspelling of "invalid"?
