[Null]

This doesn’t work cause $userid isn’t defined (i want to put this in front-page.php)

Got this:

<?php printf(__('%1$s - <a href="%2$s">%3$s</a>'), get_topic_time(), get_user_profile_link($userid), get_topic_author()) ?>

All is in a for each loop, i get the author but no link to his profile
