Chats are stored in an (almost complete) RFC822 compliant format on their servers. In plain HTML mode, you can click on a chat and do the "View plain message" trick to find what you need as email attachments: 1. A HTML copy of the chat 2. An XML log (XMPP) of the chat So you can, in theory (and I have done it), crawl your GMail account (via the Plain HTML view) and grab your chats. But doing so is against their ToS and I got my account locked down for about 4 hours once. [Hint: rate limit your requests to sneak past..] It was fun though. :)
