Hey there, if you've sent Bitcoin to the escrow address and you'd like a refund please PM me with your Bitcoin address, amount deposited and a signed message.
Thanks
Since the crowd funding has failed, any reason for not
simply sending all the bitcoins back to the addresses from which they have been sent. Why do you think someone will not want refund?
Two of the three contributions were made back in February, so I'm awaiting address confirmation to prevent refunding Bitcoin to an unused address.
