I never got to the point of actually ordering a book as the creation process was so frustratingly restrictive that I gave up. There is no ability to insert pages except at the end. There is no ability to modify the page structure or format. There is no easy ability to edit page contents. I could go on...
On the plus side, the blog slurping function worked very well, bringing down every entry and accompanying photographs. But the editing functionality was so terrible that I decided not to proceed rather than create a book the way Blog2Print thinks it should look instead of the way I want it to look.
