1. Is there a Discord server for Dwarf Fortress speedrunning?

2. If there is not one, may I create one?

So far as I know, there is not a preexisting Discord server, at least not one that is wide spread. As for your second question, I see no reason why you couldn't, the only question is would it be official. Personally, I would probably love to join such a server.

Made the server, join if you want. Moderators for this game can help moderate the Discord server if they want, just ask. Link should last, let me know if it stops working.
