well since everyone else is weighing in... Let me preface this by saying that think WFD does so much for the community here and probably deserves the benefit of the doubt.
ItsBc, I don't think it is creepy to try to contact someone you are transacting business with to find out why they haven't fulfilled their end of a deal.
I think everyone's negative reaction to this is because (1) they think it's about the GH60, which apparently it is not, but rather it is in regard to a personal transaction between you and WFD and (2) WFD has a stellar reputation here and people are reacting defensively to your inquiry and the fact that you're airing it out in the open.
If it were me, I would probably be patient for a bit longer or at least be less open about attempts to hunt him down. But I can't fault you for investigating the holdup on your personal transaction with him. I have full confidence that he will come through eventually.
I bet if this were a retail merchant like Amazon or an ebay seller, people would be singing a different tune. Just my $0.02
