mark. i wouldn't bother except it keeps re-appearing, and frankly, i'm not that great a writer though of course i'd like to think i am, but quoting me ad nausuem , well enough's enough. If you'd like to argue, well come on come on. It's how we learn. but be open in your argument, feel free to slam me, but don't threaten, and be willing to be wrong.J.O.M.
