Thanks for the Engineer joke, Mary Sheehan - I read it with particular interest as an engineer myself (Only needed the dictionary twice too) Regarding Phil Gesotti's brainstorming - are you proposing some sort of a Research project Phil ? If you can ensure a supply of 'well endowed young ladies in tank top and shorts' you can count me in - Anything for science is my motto. Regards, -- Brian Collins <[log in to unmask]>
