I don't really do discord so I've created a matrix room on my server that's open to the public. I have no idea if it will gain traction but anyone's welcome to join. You just need any matrix account (if you want a matrix account specifically on my server let me know and I'll open registrations, otherwise just use matrix.org). If you don't know what matrix is, it's this, but you can think of it as a more secure, decentralized IRC chat room. Here's the address to the room. You can use that link to join or create an account or use one of the various mobile apps. I'll put the address in the sidebar as well.
