There are, at least, two reasons =20 for which I'll have to think about it before I give an answer. 1- You say, I quote you: "the input is no harder than writing in (La)TeX." This seems to be very simple for you, but considering my very limited =20= ability with computers (and this is an understatement) it will =20 probably be almost impossible for me. For example I cannot type (La)=20 TeX. If I need to have a text typed in TeX, I have to ask to a friend =20= to type it for me. This is one of the reasons why I publish very =20 little although I have many handwritten first drafts on various =20 subjects in Category Theory. 2- Even assuming the friend would help me, the nLab is a wiki system, =20= thus anybody would be able to modify my texts. And I'm sure I =20 wouldn't like that. I'm not against discussion and I wouldn't object =20 if one or many persons wrote their own texts, even if they are very =20 critical of mine, provided they give mathematical arguments to =20 justify their objections. You might suggest solutions to 1 and 2, in which case I'd gladly =20 accept your offer. Thanks again, and best regards, Jean Le 13 janv. 11 =E0 02:37, David Roberts a =E9crit : > On 12 January 2011 17:20, JeanBenabou wrote: > >> Thus the official list does not permit such discussions.
