Publishing Genius is not going to accept submissions for books after the day after tomorrow. You can send them on 4/1, but not on 4/2. I’m going to select a book to be published in 2011 from everything in the pile by 11:59 on Thursday. Book submissions will be open again later.
(However, I recently lost a bet to Michael Kimball, so he gets to pick any book I have to publish — you can always hit him up with bribes.)
