I'll register. What should I do once I do so? Do I need to send you an email letting you know my information or something?
Once you have resisted with bitcoin-otc, I can look you up at
http://bitcoin-otc.com/viewgpg.phpI will then send you a pgp singed email that says 'I want to buy this kindle, and the terms of the deal'
You can reply with a singed email saying 'Yes that that is all good, here is my Bitcoin address for this transaction (you should use one Bitcoin address per transaction).
This means that if one of us do not hold up our end of the deal, we each have singed proof of our intentions.
Hope this makes scene, I'm looking forward to doing business with you.
