Doing it backwards: phpBB in WordPress
A popular request has been a “reverse” template integration - having phpBB appearing inside the WordPress header and footer. (Much like this site looks to the untrained eye - although WP-United.com actually uses a phpBB header and footer on every page).
Well - it’s in alpha and on its way to being released. the package will allow you to choose whether you just want the forum inside the WordPress header and footer, or inside a WordPress template page. (You could even put an entire WordPress install inside a single blog post if you so desire).
And, of course, it’s a full template integration - no iframes or any of that jazz!
Here are some obligatory screenshots:
