What I just did it set the “signup_email” input to display: none and added this script to populate the email input with the username and generate a ‘fake’ email address username@domain.com.

    window.onload = function() {
        const domain = "@domain.com";
        var userName = document.getElementById("signup_username"),
        var emailAddress = document.getElementById("signup_email");
        userName.addEventListener('input', function() {
            emailAddress.value = userName.value + domain.valueOf();
        });
    };

Very open for better suggestions 🙂

Hi metalhead, long time since your last post.
But I’ve been banging my head for a couple of hours trying to do something similar.

I’ve hidden the email field, and set a default value to it (account@email.com).

But whenever registering a new user, it’s blocked by the “existing email” error.

Have you found a better solution? Or what was your way to set the value to the signup_email?
