Sounds good. I still actively use IRC, but I understand if some people don't. Another alternative could be Telegram, which actually lets you have non-random group links for public groups, and I like it better in general, but if people here prefer Discord, that's fine too. (Telegram doesn't have voice channels if you'd want to make one, though you can send voice notes and there are one-to-one calls now. I wouldn't participate in those anyway.)
