Sorry to be so uptight, but my father is a technical writer and it was beaten into me!
Ah now Dave, were you really beaten or was it a technical
beating? That said, I am a terrible speller and I use both a
spell checker and an instant speller which is book with no
definitions but simply alphabetical lists of words. Even so, some
probably get by me because I am also a terrible typer (is this a
word, guess it should be typist.
