The increasing use of email simply exposes a problem that already existed.
And built-in spell checkers don't always help.
I have a spelling checker.
It came with my PC.
It plane lee marks for my revue
miss steaks eye ken knot sea.
I've run this poem threw it,
an Yule bee pleased two no.
It's let her perfect inn it's weigh.
my checker tolled me sew.
