What we did was to take a few screen shots with the date each month, also I printed the log of chat duaration hours for each month ( about 4-5 pages) also western union receipts and any any post mail or cards I scanned inas well. Our data went over 2 years. For the rest we added photos of holidays together, and pics of land marks like the airport, scans of tickets and hotels etc also any letters of approval from her parents etc
