A bit "Off-Topic", but I hope you will forgive me. I understand the new European "City and Trekking" construction and testing regulations take effect from 30/01/2007. Does anyone know a way for me to read just the section regarding the cycle-frame ? I can buy a copy of the whole standard from the British Standards Institute fro £148.00- (c. 230Euro, I think !!) As a pensioner, this is more than I can afford, so I am hoping to find a way to take a look at the rules before I spend too much money. Meantime, may I send my best wishes to all contributors to Python-thinking. First thing I do each evening is to read the Python List. All the best, from Ed.
