stugots, do please bother. I simply don't know !

I doubt there is anything in this world that I would have knowledge on that you haven't already got covered ..... but you never know ?!

When you pick yourself up off the floor from laughing at my extreme ignorance, would you kindly get around to the task at hand and give a "simple" middle aged / older Aussie an explanation or I'll get someone to give you a good seeing to ..... LOL !!!!!!!!!!!!!
