Good to know
- Does pre-registering cost anything?
- No. It is an email address on a list. You pay when you enter.
- Does it hold me a place?
- It holds you early access, not a place. You enter from the email before entries open to the public.
- Do I have to pick a format now?
- No. The format question is optional and only tells us what to plan for. You choose when you enter.
- Will you email me about anything else?
- Only FLATOUT entries. Every email has an unsubscribe link.
