I had a previous engagement and got home to log in apparently just moments after the audio failed. However, I just listened to the entire thing, and I was blown away! I think future audio chats would be a tremendous idea, especially if it's possible to post them on the site afterward for people like me whose schedules tend to be unpredictable.
Thanks, Robb and Elissa, for adding yet another layer of awesomeness to TPR!
