Could there be a discord server, the reason I'd like to start a game jam, is to connect with other people.
So far there’s only 13 people in the jam, so I’m not sure there would be enough people to justify creating a server for the jam specifically yet (I’m at my server limit, so I’d have to leave a server to create a new one too), but I can create a crowdforge page if you need to find team members. Also, I run a moderately sized Queer Game Dev server linked on my profile that I’ve talked about the jam in. You don’t have to be LGBT+ to join, just respectful. I also run a zine server you could meet people in if you’re creating an analog game.
I created a Crowdforge page: https://crowdforge.io/jams/Neurodiversity-In-Games-Jam
