I tried to run Werewolf: the Forsaken over an instance, and I had this MRF written called “WalledGarden” where messages can go out, but no messages can come in, and people can “react” to posts. The idea was that people can peanut gallery but won’t disrupt the game’s flow on the website, but the game site would show reacts. If players wanted to interact with people OOC they would just go into another tab for their main instance.
I bill iddqd.social as a /g/, /vr/, /tg/, etc instance as well
