Matrix chat works pretty well too.
It's ~ as convenient as Discord. More convenient in certain cases. And one might be able to easily use the API to create an Archive site for all discussions in there.
In other cases, you have the ability of encrypted conversations, which of course you won't be archiving. Right?
honestly i would understand matrix more than discord, it's a lot easier to just jump in and start existing.
