Wow, I didn't know John died. Except for the stuff by MJD John was their #1 writer, but also editor, line art coordinator, layout person. Mike Johnson mentioned to me many a time how John was a one-man publishing house.
Loosing all those critical skills was definitely a critical blow to the company as John kept products moving out ready for publication. I am sorry to hear of his passing.
Might I ask when this happened?
