  1. Why is Western Power forging correspondence?😉

    Thanks for detailing yet another coffin nail, NBC.

    My browser tells me I last looked at this PDF 2 weeks ago. There must be a few site admin’s out there wondering why random PDF’s are getting so much attention!

  2. Just making sure that we deal with the inevitable BZ arguments that Xerox somehow retroactively changed the software, unbeknownst to people, on all Xerox devices..

    When a much simpler explanation would prevail…

  3. No color fringing. I’m going to make a prediction: the vast majority of the text will not have Hermie’s “pincushion distortion” (which is actually just an optical illusion caused by the overlay of a grid on a lossy jpeg image). Certain exceptions: portions of the letterhead (WESTERN POWER DISTRIBUTION, with the exception of the U and last I in DISTRIBUTION, and the non-text portions), some of the text in the footer, and the mailroom stamp, plus perhaps a handful of letters in the main text and some objects I didn’t bother examining.

    Care to put my prediction to the test, Hermie?
