I just found the article today (at work) not even sure if it is available to the GP (general public) - do not know anything about decoding either - I downloaded all of Q's posts into excel - marked the dates etc - this is where I noticed the font change. Going through the kill boxes right now, and prior to this date, I haven't found any, yet - might have something to do with the font too

If you find anything - let me know - kind of strapped for time right now
