Thanks for all the quick responses.
Ashcroft – did you use plain white paper?
Mcartier713 - As for the endorsements, I make an entry in the remarks sections for the flight that the sign-off or endorsement is in the back. I, obviously, have an additional page in the back of the logbook that I track the date, activity, and have the instructor actually sign. That page is a running document that will remain in the back of the logbook until I’m done flying. As for events that occurred prior to changing to an electronic logbook I state in the remarks that the sign-off is in original logbook # … . It has worked great with the FAA, I think (hope) it will pass the interview test in the near future.
