You can update your information in a variety of ways.
For the hard copy Guidebook, you can cross out and re-write items, you can staple additional pages to the original page or you can go HERE to purchase a booster pack of replacement pages and include them in your Future File Guidebook.
Additionally, for the Future File software system, you can enter in the updated information on the appropriate page or pages, print those new pages separately and replace them in your print out of the Guidebook (or save a new PDF version if preferred).
