Here's a plea for some simplification of posts. There is an amazing amount of information in the user posts and in Liz's prompt and thoughtful replies BUT it is not necessary to include the entire thread back several generations of posts when replying. It makes for very large emails AND it is difficult to sort out the new info etc from the volume of repeated info. It is often very helpful to requote a sentence or two, so as to put an answer in context, but please don't repeat and re-repeat the previous posts. I thank you and my email box thanks you too. Bruce
