Here's what happened to sessions 2 and 4...BREV SUCKS AND IS A TECHNOLOGICAL MORON. Once you accept that reality, things DO get better and easier to handle.
I lost half of session 2 due to an editing mistake and session 4 due to audacity and skype killing each other. Not fun.
I do believe all of the other episodes are safe and sound, though. Fingers are crossed they continue to be!
