We’d love to self-host on our own app! Some day. :)
Matrix would be another good option today, but DEF CON was already using Discord for official communications, so this is one less app for people to install.
I'm building a publicly-accessible matrix app [0] that might be of interest to you, and anyone else looking to self-host a discord + discussions alternative.
It's still early days, but I'll probably do a Show HN at some point.
