Oo er it does seem as if my original (misplaced) comment has stirred up a bit of a hornets nest!
However, ladies and gentlemen, nobody has yet answered my original question/request, namely is PPRUNE a bit of a misnomer and does anybody have any ideas vis a vis a better and more representative acronym! I am still too dull of brain to come up with anything! (6 pints of wife beater and 3 moscow mules to the worse).
