All,
Shell Management ("Mollusc Management", as I prefer) appears in many PPRUNE forums, and elicits similar responses from many subscribers. My advice fwiw, "Don't react....while you're re-acting". There are those, who just for the intellectual fun of it, will always take a contrary view, SM is one of those. Don't encourage him or feed his habit, ignore him - and he'll go away.
