Ada North Pool had the great honor of being asked to join the friends and family testnet. The TLDR is the progress is great. Overall the experience has been great and documentation, features and overall experience is shaping up well in the opinion of this pool operator.
We also added a hardware encryption usb drive in preperation of cold staking key storage.
The nodes come prebuilt with a lot of features that can be enabled. For example the EKG view that you can set to a port on your localhost.
