Yeah, I just took screenshots of the logged dates/times of some of our calls and printed them, too. You won't need to print off loads and loads; just show that you've been in steady contact with one another. You can take screenshots of your e-mail inbox, too. They don't need to see the conversations, but you know, the main screen of your inbox showing your subjects with the dates. How long will you have been apart by the time of your application?
