I don’t know which ones you had problems with but it’s worth noting that some automatically echo and some don’t.

<?php user_profile_link(); ?>

=

<?php echo get_user_profile_link(); ?>

If they’re get_anything then you have to echo them yourself, if they don’t have get_* then it’ll echo on its own.

[Edit] Also remember most functions don’t need a $user_id passed as parameter but won’t work in this case unless you do pass it.
