Stefan asked 'How many neuros does it take to change a light bulb.?' On a question of such importance, I thought that I should seek an authoritative answer, so I phoned the headquarters of the UK PDS. Unfortunately they were far too busy to give me an answer: Aparrently they had just had a bulb failure, and were putting together a series of courses to teach people to see in the dark! -- Brian Collins <[log in to unmask]>
