Good news, some miner finally decided to confirm the transactions. Your message is now saved in the block chain.
By the way, I have been working on the new version of cryptograffiti for quite some time now. I will start working on the write tab in the near future and I plan to make automated message encoding more user friendly. For example, the users should have the possibility to include their chargeback address so that in case of problems it would be easier for me to send them back their bitcoins. Also, I will have to upload the raw transaction hex in addition to the transaction hash so that the user could immediately verify that their order has been filled indeed and even broadcast the transaction manually if needed.
This new work in progress cryptograffiti is available here:
