Discord ain't it. There's got to be folks over on this instance e.g. that would be interested in setting up a Shadowdark community, right? Right?? I don't want to contribute to enshittified reddit's bottom line, but the Shawdowdark subreddit is one of the only reasons I still open up that tab every now and then...
The arcane library discord I find quite lively, but i also do miss conversations that are more structured around topics rather than channels. Are there any good blogs you are aware of?
