Time zone

Expected participants (optional)

The start and end are on the clock of the time zone you pick. A contest may run for at most 12 hours, and must start at least 24 hours from now.

Anything else (optional)

I agree that my name, organisation, email and phone number are stored so that this contest can be arranged, and that they are used for nothing else. They are visible only to the people running this platform, are never published, and can be deleted on request. The address this request is sent from is also recorded, to spot abuse of this form.

Nothing is booked until we confirm it. You will get a link to check the status of your request; keep it, because it is the only way back to it.
