My WordPress blog book is missing post, how do I get those post to appear?

It could be that the "Sticky" option for your post is selected. This will prevent the post from carrying over to the book.

You can log on to your blog to edit the post section. Here you will be able to deselect the "Sticky" option from your post.

Once the changes have been made, you can log on to Blog2Print to create a new version of your book with all of the posts.
