Waitlist
Leave the list
Type the address you signed up with. It comes off straight away. No password, no confirmation email, and nothing asking you to reconsider.
The list holds an email address, the date it was added, and which launches it is waiting for. That is everything.
Nothing else changes
The list has never affected the software. Every tool works the same whether you are on it or not, and it was never used for anything except telling people when something ships.
If you would rather ask a person, write to [email protected] and it gets done by hand.
