Sector8 Dear, on what basis do you think I'm non-NATS and a creep?. .Hope you don't make work decisions based on such guesses! <img src="eek.gif" border="0"> . .I was adding an extra question on the back of yours as I was genuinely interested if LW was paid (with thanks to eyeinthesky for answering).. .Whilst I'm on my soapbox, thanks to Bexil for your post- very interesting, and I'm delighted (and surprised!).
