Re: OK not Okay?
I've heard all kinds of variations on the etymology of OK. Most recently, I guy tried to persuade me that it was from from Scots och aye.
The usually useless Wiki has a pretty good wrap-up of where it really came from.
IMO, it was an abbreviation but has now become a word of its own, and thus is valid in Scrabble. The English language mutates. It is not under the control of any one person, organization or country. Get used to this concept pedants, you'll sleep better.
