My friend RobinNewton? pointed me at all this. I am frankly impressed at an excellent information-sharing mechanism. You can find my scribblings on the web at http://www.chaos.org.uk/~eddy/ , and if you know of a mathematical wiki, please tell me where to find it - eg by adding to this page ;^)
Hi Eddy - are you the Eddy I knew at Cambridge? Do you know Andrew Lipson? Are you still here?
