Right now bbpress appears to default to 15 post per topic before being paged. Where is the variable to reset this to another value?

try this if you want to change the number on the front page:

Never mind, I found the variable in config.php. Pretty obvious.

'// The number of topics that show on each page.

$bb->page_topics = 15;
