I'm an admin for The Dere Types Wiki, and I want to know how to have a Discord by the chat. I recently created a Discord for the wiki, and I've noticed that in wikis, they have discords right by where the wiki chat is. For instance, on a random page on the Polandball Wiki, notice how on the right of the page how they have a Discord? It's the same for a page on the OK KO Wiki. How do you make a wiki Discord go where the chat is?
