Greetings. I have been working on the design of a large-scale hypertext for mathematics: a linked structure of Web pages of mathematical writing. A paper on the design issues and proposed architecture of a mathematical hypertext, at http://jodi.ecs.soton.ac.uk/Articles/v05/i01/Mayans/ may be of interest to math-funsters. This is a very large and long-term project. A first text, in linear algebra, is in the works. The starting point of this work is the question: what is the ideal way to write mathematics? I'm looking for thoughts, suggestions, and maybe collaborators in this work. Bob Mayans
