How can I check if I am on a forum page or forum post inside my theme. I am using the bbpress plugin (not standalone bbpress). There should be some conditional like is_bbpress() or something?
This page explains the is_bbpress() function. http://codex.bbpress.org/theme-compatibility/getting-started-in-modifying-the-main-bbpress-template
It also details another way which involves creating a new template which matches one of the key names for example forum.php. Than all forum pages will be loaded with that template rather than page.php, meaning you don't have to use is_bbpress() to test if it's a forum page anymore.
