- What is a fingerprint?
- Every username in Arqo gets its own drawing of the Arqo spiral. Same spiral, never the same drawing. Yours is made from your username, so it is yours for good.
- Is my username really reserved?
- Yes. Nobody else can sign up with it. Sign up with the same email and it is waiting for you.
- Is my email shown anywhere?
- No. Your username is public, like any handle. Your email is not.
- Can I change my username before I sign up?
- Yes. Come back, pick a new one with the same email, and it moves. One username per person.
