If you are working together as a team then remember to add team members as admins of the game page that you are planning on submitting to the jam. This way they are also allowed to vote.
Is that something that happens once the Jam has officially started? And once you have submitted a version of the game, can you update your submission later if the jam is still open?
What happens to the pages after the jam is closed, do they remain here forever?
I think you need to add the team members as admins to the project page before submitting, but I could be wrong. Best to do that to be sure :) This is the first jam I'm hosting so I am not 100% sure but a quick search tells me you can update the game up until deadline. The project page you create is attached to your itch.io account and stays there as long as you want. The jam results/submissions page stays online as long as the host want :)
