P.S. To the moderators: hopefully this thread has now served its purpose.
]]>I believe that I'm in as good a position as anyone on either forum to comment on your question, and I have an account on Math.SE (under the username Matt E) as well as here on MO. I will try to address your question on Math.SE soon. Thus there is no need to repost your question here on MO.
