Hey, if anyone is interested, there's a fairly decent-sized server in Discord for the Year Zero Engine. There are over 100 members so far, and there are channels for all the games, including Coriolis.
I make YZE games (https://drivethrurpg.com/browse.php?author=Matt%20Kay) and produce predominately Free League content on my YouTube channel (https://youtube.com/@3skulls)
