Re: Showing more tags on Heatmap.
I have this near the top of my front-page.php:
<p class="frontpageheatmap"><?php bb_tag_heat_map(); ?></p>
That’s where you would make the modification.
front-page.php does not use tags.php. Those two different php files do two different things. tags.php displays this: http://invictatrader.com/bbpress/tags/
front-page.php displays the front page of your forum:
And the tags are just a small part of the front page, provided by the function
bb_tag_heat_map();, called with whatever parameters you want.
