Yes, Facebook really is great because apart from chat history (why don't they work on that?), all messages and wall posts you send and get are there, unless you delete them of course. It's just a pain to find things that are very old there, as well as a pain to get that stuff into a printable format. As far as regular emails, I think Gmail is the best thing to have for these purposes. As long as you don't delete anything (and you won't have to because they give you so much d @ mn space), it will save emails and chat logs for you to your heart's content. With landline and cell phone companies, sometimes you can even request records if you are no longer a customer (you might have to pay though). The joint back accounts this is great, but unfortunately not pertinent as it looks like the IO wants evidence *before* the relationship got to the meeting stage (and I sure hope they didn't open a joint account before meeting, lol). I'd add: just spend some more time thinking back, and make an index. Good luck.
