Thank you my dear friends. David has had some setbacks in his life lately and my wife Lee had a breast cancer operation 10 days ago. While the prognosis is good, it is a scary time thinking I might lose her. Thank you to all the members that answered questions and looked after things when David and I weren't right there to get your posts out of moderation. We try to keep the disruptions to a minimum but some days, stuff happens. We've got a great bunch here. Thanks for understanding.
