Just gonna add that in the meantime, I think "accountability.biblepay.org" should be way more advertised. It does not provide enough information alone (how to prove documents are not fabricated, reconcile BBP amount sold with proposals, other charities, etc.) but it is a good start.
Yes, you can click on the link in the wallet but that would assume I already have installed the wallet which I wouldn't do before "checking" the coin. I think that URL should be somewhere very noticeable on the official website and in the OP too.
