@Cam. I am not a FPer. That's the other people in my study group. I might learn from them, though. And I pointed them at this class, so maybe somebody else might join.
P.S. love the "singing aboard the ship". The other study group is in Secure Scuttlebutt, where nautical metaphors abound. https://staltz.com/an-off-grid-social-network.html
