Re: WordPress and bbPress Theme Integration
Do users have to log in at the blog and the forum separately, or are the logged into both simultaneously? I didn’t think that 0.9.0.2 and 2.6.2 were cookie compatible, for logins.
To do what you’re describing, you need to design a theme for bbPress that matches your WordPress theme. Short of doing that, you can include WordPress inside bbPress to have access to WordPress functions (like get_sidebar, get_header, get_footer.)
You can also browse the tag integration to see how other people have approached the problem.
