I am just waiting to figure out how to sign a message. It would be easier for me to just put my spreadsheet order number at the end of my transaction. e.g. BTC 2.101300XX

I was also hoping John would show up and confirm the transactions are coming in like he wants.

The message signing process is only to prove you own a certain bitcoin address.
You will want to sign the message right after you send payment. Once payment is sent, copy the bitcoin address you sent the payment from and copy the transaction ID to enter in your message.

If using bitcoin-qt:
Click file, then sign message:

In line 1 - enter the bitcoin address you sent the payment from
In line 2 - construct a detailed message based of the example shown below. Best to use details about the payment sent including transaction number etc.
Then click the button labeled sign message (3)

After you click that button, you will get this message:

Now, email all three of these fields to Arklan:
-Address you sent payment from that you used in line 1
-message entered in line 2
-signature that bitcoin-qt populated.

On Arklan's end, he will use those 3 pieces of information in the verify tab and it will confirm that all the information is correct.

Do not make any of the info public. Make sure everything is copy and pasted verbatim. Make sure only the seller knows this information.

Hope this helps.
