Syntax error in code example

Hi,

The code example to register a new user contains a syntax error. Please change as this would help beginners to get a faster success.

Wrong:

{
    "username": "your-username",
    "email": "[email protected]",
    "password": "0000",
}

Correct:

{
    "username": "your-username",
    "email": "[email protected]",
    "password": "0000"
}
