I didn't think that your spelling was that bad

It seems that the spell checker is either integral to Firefox 2 or somehow in the bowels of my computer - I can't find how to turn it off. Regarding old English spelling, I know that "color" was used many years ago, but I don't know about "neighbor" - most probably. There should be a smilie after the word "bad" above - we shall see. A friend does one with a little round nose like this

How daft can I get?
