            required: true,
            message: 'A valid email is required!',
            test: /\S+@\S+\.\S+/ // a basic regex for testing emails, don't use in production
        },

                } else {
                    next('Val was not expected value.'); // error string, if left blank defaults to validator message

        }
    })
}

app.post('/register', checkpoints.register, function(req, res) {
    if(req.checkpoint.passed) {
