Re: add the bbpress forum into a wp page
This is not possible with bbPress as far as I know. bbPress does not live within WordPress or on a WordPress page. It’s not a plugin for WordPress. You can integrate bbPress to get single sign-on (shared logins) between bbPress and WordPress, and you can have access to WordPress functions in bbPress, so you can use get_footer(), get_sidebar(), get_header(), etc. But, it doesn’t work they way you are describing.
