I met him at Nationals, and I recently made a trade in which he responded to his PMs very quickly. His name is Josiah, and his brother is also on the boards (Jmbeers). I also know he is on the boards fairly frequently, so maybe your best bet is to post whatever you are trying to PM him about if that is possible (i.e. not too private info). Hopefully he'll look into a thread with his name at the title (I would certainly look at a thread titled Professoralstad).
