Hey Colin,<p>I really like the idea of this! I have a couple questions:<p>* Do you support any sort of formatting for the contents of the book? e.g. Markdown, LateX, ? Or is it all "subject": $email_title, "text": $email_body?<p>* Do you have any estimate on how much text fits in a 5x8 book? Does your printing service scale the width of the book based on contents? Aka, if I wrote "walked dog, ate food", every day, would I get a pamphlet? Is there some kind of upper limit?<p>* Do I have to buy all my cheat days up front? It seems like you could charge "absolutions", maybe even at the end, maybe something like $0.50 for non-prepaid days? It might help people throw good money after bad :)<p>Thanks for sharing!
