I don’t know of any either and I’m on like 40+ servers probably. I’ve run our weekly dnd on it for years without issue after trying the other options. Get that it’s not good for tracking and documentation but it’s pretty damn good for active niche interest communities.

The music production servers I’m on are a perfect use of the platform IMO. There’s a server run by a guy who manufactures an open source tracker device, and there’s channels where people post works in progress, get help from others, there’s streaming events where people can submit songs they’ve made using the device, etc. There’s a bunch of people popular in the music scene who regularly help noobs. When people are like “Discord sucks use my favorite platform instead” I’m just like I don’t care about the platform that much I wanna be where some cool shit is happening and your platforms are fucking boring.
