    I have been polishing the entry Chevalley-Eilenberg algebra on my personal web a bit.

    I thought it would be good to announce here what it is that I am currently thinking about. If nothing else, this will explain which entries you all see me working on here and thereby maybe facilitate interaction more.

    So currently I am thinking about the sought-for proposition that is now stated in the section Properties at the above entry. It sure looks like something like this proposition ought to be right, but I am not there yet.

    I have now what for the moment looks like a proof to me (still talking about the page Chevalley-Eilenberg algebra). This has been affected by DC Cisinski's indictations over at MO, but what I have looks (once again) more complicated than the elegant statement he seemed to have in mind. I am probably still missing something.

    For instance I felt the need to use the injective structure on simplicial presheaves to show that cofibrations are preserved.
