I've already had one deleted previously, because of the intermittent nature of the frequency that 4SD is able to read messages. He only has wifi access when he stops at a marina for fuel/servicing/food, etc.. He was at a marina today when he checked messages! He read a previously cryptic message I left on the general board (which was not deleted), and was able to read between the lines, then sent me the PM message that I posted! So for now I'm just hoping someone here will PM him so that he has the information next time he stops at a marina!

Thanks for the suggestion though!
