Drauk,
I've done that but too me this is pure compromise. This way, every time I spell a word incorrectly, I have to grab the mouse, go back to the word, click on it and select the correct spelling (or mannually edit the word). With the 'check spelling on send' option, the checker highlights the word and offers the options automatically. MS Outlook manages it, this seems like one instance where MS is better than OSX - damn, it hurt saying that
