I have asked him and hope to have a reply soon. In the meantime, I have fully complied with his requests. His house, his rules after all.
The request that I remove the link from my sig and post no further links to this website (reviews, DIY, whatever) doesn't really irk me as much as being it referred to as "commercial". The closest thing to "commercial" on this website are the links to
CameraQuest!
I do have a PayPal donate button on the main page and however nice it would be to cover hosting and time costs I don't even actively seek donations beyond the single button on the front. And since no product is offered in exchange for the a donation (beyond my deepest thanks, which I would prefer not be called a "product"

that can't be considered commercial.
I'm going to bed.
