John Robie- Any Input On Him?

John Robie has advertised in Linn's for years. He offer US approvals and want list service. I sent him a WL two weeks ago and thus far- nothing. He has no Email address, is apparently in his mid 70's from my research and perhaps at this point is picking and choosing who he wants to do business with. That is his right- but I'd think he'd let me know if he cannot be of service. I am probably being impatient but was wondering if he has any other customers on this board- is this a typical delay for him?

I am an APS Life Member and sent him that information.
