Absolutely, this is essential!

Nice idea.
Not essential, but it could be helpful to incentivize the consuming content/finishing tasks.

I suggest you to add it as a feature suggestion on the roadmap, so we can upvote it.

Currently I wrote a easy Code-Snippet to redirect new users (first login) to a specific post, with a welcome message and some important informations.

Perhaps this will help some people until an update is released:

add_action('fluent_community/portal_head', function() {
    // Stelle sicher, dass der Benutzer eingeloggt ist
    if ( is_user_logged_in() ) {
        $user = wp_get_current_user();

        // Überprüfen, ob es der erste Login des Benutzers ist
        $last_login = get_user_meta( $user->ID, 'last_login', true );

        if ( empty( $last_login ) ) {
            // Setze das Datum des ersten Logins
            update_user_meta( $user->ID, 'last_login', current_time( 'mysql' ) );

            // Weiterleitung zur gewünschten Seite nach dem ersten Login
            wp_redirect( 'https://REPLACE-HERE' );
            exit;
        }
    }
});

And this code I wrote to dont show this post/group in menu:

add_action('fluent_community/portal_head', function() {
    echo '<style>
        .fcom_communities_menu:first-of-type {
            display: none;
        }
    </style>';
});

William Beem but for sure, your idea is much more better than this temporary solution 😀
