I think it's a great idea and I have no objection. Wikibooks has a draft of a book about category theory at http://en.wikibooks.org/wiki/Category_theory and a stub for course notes at http://en.wikiversity.org/wiki/Introduction_to_Category_Theory It wouldn't be a good idea to simply replace what is already written there with the intro part of TTT but some of it could be put in to cover additional topics and provide more examples. I have done some work on Wikipedia and need to warn you that pretty soon what you wrote may be changed in many ways, in the small and in the large ; if you are anal about what you write this can be upsetting. In any case the original TTT will remain on the web as it is. On Fri, Sep 19, 2008 at 5:21 AM, Michael Barr <barr@math.mcgill.ca> wrote:
