Contact Information

Your email must always be a real, valid address.

Your e-mail address is particularly important:

  • It's also your login id.
  • We'll use it to send the account activation e-mail.
  • We'll use it to tell you about the status of your orders.
  • We'll use it to tell you when updates of your PDFs are available.

If checked, we'll use e-mail to notify you about updates to your orders and products. For example, we'll send you an email to tell you an ebook is ready or an order has shipped if this option is checked. If you do not check this box, you will not receive notifications when an ebook is created, or when a beta book has been updated.

If checked, we'll send you announcements of new books and other products, special upcoming events, and occasional discounts and other promotions. We hate spam as much as you do, so the volume will be low, and we hope it will be interesting. We will not give your e-mail address to third parties. If you've unsubscribed via an email link (not from this page), and you wish to subscribe again you may have to uncheck the box above, save, then re-check it and save again.

or No thanks (I don't want to track my orders.)
