Kudos on the wording of your service. An interesting way to look at the digital currency. The privilege of having your number / name saved in a community ledger.

The intention of my post however is to ask if you have an alternate way of confirmation besides PIN by cell phone. I for one do not use of them sorts of location tracking machines.
Do you allow for one on one communication and trading on that level?
Example: Buyer sends email to sales@yourdomain, seller sends paypal invoice with "hall of fame" or what have you. Buyer pays invoice and seller sends BTC.
I suppose that method removes some of the anonymity of the system but that's the price you pay.
I dig the paranoia around the whole paypal charge back Nonsense.
Do you think selling entries into the HOF ledger could be used to dispute a charge back?
(imho you should pretty up your site a bit, throw some illustrations or pictures in there)
Keep on Keeping on!
