Solicitation of Opinion.
I've spelled it "grey" for as long as I can remember. I do recognize "gray" as an acceptable alternate spelling, but my preference has always been to spell it "grey". Spell-checkers always complain about "grey", though. It turns out that "grey" is the British (and possibly Canadian) spelling. I must admit that I'm an American. What should I do?>
I wouldn't consider writing "behaviour" or "colour" - those spellings are simply too obviously wrong. Do you think "Brit" when you read "grey"? Please share your thoughts.
