Yesterday I created the jam https://itch.io/jam/punyjam1 and I can't find it in the jam calendar. I've checked "Publish" and have not checked "Unlisted". Any ideas?

(I have read the document on getting indexed)

Because game jams have to be seen by an admin before they show up in the calendar. For some reason, that's not in the game jam FAQ, but it's often asked here in the community.
