So the Kickstarter campaign has closed, fully funded and then some.
There will be a very small pre-order window sometime in the next couple of weeks, where you will have one last opportunity to secure a book set. This is offered for the people without credit cards that could not pledge to the Kickstarter, or with Discover cards which Kickstarter does not accept, or people who just plain missed the boat.
The preorders will be taken via PayPal, and as I said, the window will be very small (likely 48 hours). Stay tuned to my Twitter feed (@TimCAD) and the front page here for specifics.
