Sharing Pages and Notebooks   Sharing Pages Using Page Bundles You can share pages with other NoteBook users by sending them a Page Bundle.  A Page Bundle is a collection of pages copied from one of your Notebooks, along with all of their attachments, bundled up into a file that cannot be mangled by e-mail systems. To create a Page Bundle, turn to the page you want to share, press the Option key to change the Notebook’s title bar icon to a Page Bundle icon ➊, then drag the Page Bundle icon from the title bar to a Mail or Finder window ➋. When another NoteBook user receives the Page Bundle, they can double-click it to open it, or drop the bundle on one of their Notebooks to add its pages to that Notebook. Page bundles have the file extension .nbpb, to distinguish them from regular NoteBook documents.  They also have a different file icon.     Sharing Notebooks via E-mail Because some e-mail systems “mangle” Notebooks, you should “zip” or “stuff” them before including them in an e-mail message.  For example, locate the Notebook you want to e-mail in the Finder, then choose File → Compress to create a zipped version of the Notebook that you can then send in e-mail.   Also, before e-mailing a Notebook you may want to reduce its size by removing any “discarded” attachments, using the Discarded Attachments Multidex page.
