re;What I don't get, Milum, is why you spell humor humour.

it could be an affectation, or just because he is in the spirit of the anagrams, or maybe, just i spell grey (correctly, our friends of pond pointed out) and not gray -- (and actually i use both) it might just be something Mr.M does just because he does.

Mind you, i think spelling is hard enough with out extra letters, and would be pleased with fewer, not more letters, 'nuf said!
