Subject: RE: BS: How common is this in letters & emails?
As long as we are discussing initialisms, I still have not found any attribution of RTFM that goes back further than Dick Greenhaus's. He said that he heard it from a veteran at his engineering school between WW II and Korea. Anyone have anything earlier? Dick's citation definitely predates Wikipedia's citation of the earliest written usage as being Korean War.
