This was going to be a question but i figured out the answer so i thought i'd post anyway for those having the same problem.
Upon installing the Advanced forum module, it doesn't show the title or the taxonomy by default.
However some themes show the taxonomy and some don't, namely:
bluemarine: no
chameleon: yes (after the first post)
garland: no
marvin: yes (after the first post)
minnelli: no
pixture: no
pushbutton: no
To make the title always show (it doesn't in pixture), copy the file /advanced_forum/any_style/advf-forum-post.tpl.php to your theme directory and remove the if and endif statements so that this section:
<?php if ($title && !$top_post): ?>
<div class="post-title">
<?php print $title; ?>
</div>
<?php endif; ?> looks like this
<div class="post-title">
<?php print $title ?>
</div>Then to get the taxonomy to show you can add "print $terms" like so:
<div class="post-title">
<?php print $title; print $terms ?>
</div>This is based on a post by the module's developer at http://drupal.org/node/383116
