By following this reference Integrating WordPress with Your Website

yes, i get it work in /forum simply with this lines of code:

<?php require( '../blog/wp-load.php' );
query_posts('showposts=3');
while (have_posts()) : the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a><br />
<?php endwhile; ?>

but in a different domain it doesn’t work.
