To be honest, I don't like the misleading subject. It clearly states a very positive result and leads one to open the post trailing it with 'but' ... add the links to not only the sales page but the affiliate page, as well (which has no bearing on conversion) ... and I'd think it just as much an attempt to recruit affiliates on a busy section of the forum than asking for help with conversion. Of course, I may be wrong.
I also believe constructive criticism can come in many forms, whether blunt and straight forward (Curtis) or motivational (Victor) ... both can help if they lead to a positive end result when put in motion.
