Re: bbpress INSIDE theme?
The easiest way now would be to look at the bbPress-live plugin at https://wordpress.org/extend/plugins/bbpress-live/ and use the new xmlrpc functionality to pull the information in. Just create a new WP page template file to use for a new WP Page. There is more documentation on the plugin page, but kicker is that it requires 1.0 alpha 4 at minimum. As for including bbPress as a WP page, I don’t think I have ever came across instructions that work…..
