Sorry I was sort of away for a short while, been busy with certain important things and could not respond earlier.
Ian, I agree this should have been my responsibility, so thank you for suggesting it first. I not only expect folks here to discuss the thread but also come up with suggestion on how to improve it, so that we could have this kind of activity on a regualar basis.
I also agree the question should not be too difficult otherwise the thread gets stuck and takes a long time to finish.
I hope someone with have the answer and the ball starts rolling in the thread again. If not Chris you may answer it and post a question also.
