Indeed. If I were to hazard a guess, I would say that every possible angle of CRLF handling has been covered in one thread or another in the last month or so. Let's leave this all in Eric's capable hands. I'm confident that whatever he comes up with will be better than where we started and a vast improvement overall for everyone. From what I've seen so far, and what Rob's results would confirm, is that the changes made already are a giant leap forward. Obviously if there turns out to be a flaw in the delivered result, I am also very confident that someone on this list will find it and report it. Until then, we can all bask in the bliss of an issue well-covered and the lack of a need for further email on the subject. :-) -- Larry Hall http://www.rfk.com RFK Partners, Inc.
