So I definitely cannot speak to any association he had you'd have to ask him. Not sure on the timelines either. He was definitely not the co founder of Cryptsy haha.

According to Marshall Long he is, or does Cryptsy allow anybody to claim to be a co-founder of Cryptsy sans evoking a cease and desist order?
So he said it on more than one occasion when he was CTO.... I think hes implying he helped with the Canadian site so you can run wild with that one.
