I disagree that this is only a simple yes/no question. Well the ultimate answer is either yes or no, but you do need justifications. Think, for example, if some user posted another answer saying "No, the “cosets” in his notation are not the orbits under the right-action of $H$" Then what should we do?

In cases where this is important to you, then imo your OP here has a clear answer: post the partial progress as part of the question. It doesn't matter how long it gets.

a friend set up some web pages for me, mostly intended to hold pdf's rather than more links. My best question was my first on MO. https://mathoverflow.net/questions/12486/integers-not-represented-by-2-x2-x-y-3-y2-z3-z I was able to link to various write-ups there and relevant articles, already downloaded there.
