Should have known something was wrong when Cross didn't answer phone calls or reply to a PM.
Those of us who shared time and efforts with Greg will miss him in very special ways, for he was an uncommon person. I admired his skills and knowledge in some important areas, and his forthrightness. Anything else that came with his exuberance was simply another facet of a very experienced and complex man.
Some of us are hoping - and trying - to see that his passing is observed with proper remembrance.
