I just burned through all 27 episodes of Discern Realities and am now tackling +1 Forward … are there only the 8 episodes I found on The Gauntlet website?

The first one is about AW2 but the way Richard Rogers starts the cast sounds like this is a well established format… are there previous episodes?
