Network News Transfer Protocol
Usually intended to deliver UseNET News, it is a multicast interserver protocol more or less according to the federation principle.
But psyced implements none of that as it has its own multicast strategy. psyced only provides client access for NNTP clients, and it only lets you inspect threads of a threaded place as described somewhere in Create Places.
You need to have a UNI subscribed to some threaded places to even start seeing something.
Not sure if it actually works, but hey it's another great playground!
