Everybody who remixed the sign-up sheet is in the Octo Games.
When the form asked you for a number, it was asking for a 3 digit number. If you answered less or more than that, it was automatically turned into a 3 digit number. For example, if you said "10" it would be turned to 010. If you said "2" it would be turned to 002. If you entered 1234, it would be shortened to 123. Everybody is in.
