Re: changing required fields for new students

Go into lib/moodlelib.php and search for

function user_not_fully_set_up($user) {
    if (isguestuser($user)) {
        return false;
    }
    return (empty($user->firstname) or empty($user->lastname) or empty($user->email) or over_bounce_threshold($user));

}

and delete the part: "or empty($user->email)"

so your return string looks like:

    return (empty($user->firstname) or empty($user->lastname) or over_bounce_threshold($user));

Hope that helps.
