Context: there is an internal project developed by 5 developers (including me) over a couple years; now the other guys have left, including the PM. Management of the project is passed to another PM, who was working on a related project. He doesn't pay much attention to my project, because he is busy with his own, it's kind of a rush situation there... or may be other reasons. The old PM is supposed to "support" the project, but he doesn't pay much attention either. He's difficult to reach.
So... how do I answer this letter? How do I deal with the whole situation?
