Ladies and Gentlemen, Can I please, please ask you all to change Subject lines to something more meaningful please? One of these days, you or others will be needing to look through the list archives, and become decidedly frustrated knowing that what you desperately need to find is buried behind a totally meaningless Subject. Many thanks for your co-operation.
