I discovered CH through a website Rob had with Batch file info back in 2006. He had a website that might have been his own site and then there was a reference there to CH that I checked into and I have been ever since.
Ages ago I use to mess around with batch files and Microsofts Undocumented Features M.U.F's and somehow I came across Rob's batch info.
