...LOL xD
They're not going to look at all that, come on. If you want to condense it to just a couple represent sections of conversations, I think that's fine. Just highlight the dates if they appear anywhere so they see 'oh this is when'. Other than that they don't care. Emails will also work, but I think they'll be more interested in seeing pictures, new flight details if you're going to have any, phone records, etc. too. Just try to have as wide a variety of samples as you can without overdoing it. Either way you're going to be fine.
But don't give them 130 pages of conversations.
People keep getting danged BOOKS published on their online relationships and making bunches of money just off of their old chat logs...kind of makes me mad just because I didn't get there first
