It depends on where you want your shout box.
Assuming you’ve installed and activated it per instructions…
Got to:
admin -> presentation -> theme editor
Note – (theme files must be chmod 666 to edit)
If you want it in your sidebar – click on “sidebar” on the right side of the screen. This opens sidebar.php to edit.
Now find where you want your shout box. For example if you want it under your search box – find the search code:
<div class="sb-search"><h2><?php _e('Search'); ?></h2>
<?php include (TEMPLATEPATH . '/searchform.php'); ?>
</div>
Right below this, put your shoutbox code inside a div like this:
<div>
<?php shout_box() ?>
</div>
Now if you want like a Shoutbox “page” go to:
admin -> write -> page
Give your page a title like “Shoutbox”.
Now in the text entry box put your shoutbox code:
<?php shout_box() ?>
Click save and that will do it.
