A timed challenge for one school. Students of that school who sign up after you create it join automatically (earlier students get a Join button). Participants can only play while it's live; afterwards their progress is frozen and the Event tab shows the final standings. Times are in your local time zone ().
Students from other schools join the event picked here as guests: new sign-ups wait in the list below until you press ✓ Approve + 🎉 event; existing students get a 🎉 Add to event button.
