Project Kindle Store Get Books In has begun:
I started with Hunter because it was already in .mobi format, and it's my most recent thing (it's still in pay-what-you-want-even-nothing format, incidentally.) Assuming the world doesn't implode around me, I'll get Sunken Treasure in the Kindle store next.
Also, while I did this, I made myself an Amazon Author's page. Neat!
