You appear to be exasperated. Your wisdom is valued by this rapidly growing post, I appreciate your idea and that's why I contributed. By all means get those stupid questions referred back to the whole context of the post. Unfortunately newbies clutter the post because they do not read the whole thread. My answer to them is to do exactly that. Don't let the people who won't do their homework wast your time by replying. I invite criticism of my post. We all learnt that way and I realise that you contributed because of the others before you who played the game. Great job tk5.
