The latest issue of New Scientist [2nd Feb 2002] has a very interesting article on Open Source. The lovely thing is that it is the very first magazine article they have ever released under a copyleft [i.e. an Open Source licence] For this reason you don't need to buy a copy of New Scientist. Go to http://www.newscientist.com/hottopics/copyleft to download the article. Nigel -- Nigel Pauli - I.T. Manager St. John's School, Northwood, U.K. http://www.st-johns.org.uk/
