@dunlix yes, but there is also a register and login link in the message

Hi, Can you point me to that location, where I can find and extend the USER model, to include the USER EMAIL ADDRESS ? The expectation is that the EMAIL ADDRESS should be persisted in the DB and be available across USER login sessions.

@akumbhare This can be done in latest versions. It's under Settings > Guest. Just tick allow guest handles. It doesn't ask for an email, just a username.
