Hi,  maybe there is like a discord or some sort of chat for the participants of this jam?

If it is done. What to do?

If anyone wants to chat generally throughout the jam, you can join my discord server - https://discord.gg/cCsCbNJ . I hope the creator of this event won't be mad for this.

Great idea - joined!

Be sure to enter the gamejam channel :)

Not mad at all. It's a great idea!
