add_action(‘init’, ‘er_add_default_boxes’);

function er_add_default_boxes() {
register_taxonomy_for_object_type(‘category’, ‘easy-rooms’);
register_taxonomy_for_object_type(‘post_tag’, ‘easy-rooms’);

As ther’re to many user that don’t need it at all I think it would be a waste of loading times to add it by default.
