Any idea how to do this? It's only showing around 100 characters, I'm looking to show 500 or so but I can't find a place to change it.

Any idea? I tried looking in tpl_reviews.default.php and changing the 60 and 100 on this line:

<div class="content"><?php echo zen_break_string(nl2br(zen_output_string_protected(stripslashes($reviews->fields['reviews_text']))), 60, '-<br />') . ((strlen($reviews->fields['reviews_text']) >= 100) ? '...' : ''); ?></div>

But it had no effect
