Answer 1

Write this into a plugin:

add_action( 'template_redirect', 'auth_redirect' );

As plugin on GitHub.

This will force all visitors login if they aren’t already.

You probably just have to put the following in your functions.php:

if ( is_user_logged_in() ) {
    echo 'Welcome, registered user!';
} else {
    wp_redirect(site_url('/wp-login.php?action=register'));
    exit();
}

If you don't feel like changing your code, you could use this plugin instead: Restricted Site Access. It's highly rated and in my personal experience, it works really well.

Limit access your site to visitors who are logged in or accessing the site from a set of specified IP addresses. Send restricted visitors to the log in page, redirect them, or display a message or page. A great solution for Extranets, publicly hosted Intranets, or parallel development / staging sites.
