I agree with Woodhouse, but still about 14% of all wikis use Chat, almost all of which have people without Discord, so some kind of internal replacement for a real time chat has to be worked out for that one-seventh of all wikis.

edit: I do like the "micro-chat" feature someone suggested. You could create a very bare-bones replacement of chat with minimal UI and just a few dozen characters per message, and they could be threaded. This would function for people without discord and slack. Of course, such a thing would have to be ported to Gamepedia too
