That's right, as explained in lots and lots of topics, jams have to be seen by staff before they show up in the calendar. Please wait.
Viewing post in Game Jam Not Showing Up After Multiple Days
Hello! Jumping on this as I started a Jam a couple of weeks ago and it still isn't showing up on itch, you need a direct link to it. Also, I've noticed someone made a post on the community page but I can't interact with it at all; I can only edit or delete it. Has my account been banned from hosting jams? When I click on the Jams tab and then "Jams Hosted", nothing shows up. I have to go into my jams dashboard to see it.
I'm just confused as the Jam q&a has no guidance on this? thank you.
