WP-United is a toolkit for synchronizing WordPress and phpBB3 content. It comes as a phpBB3 mod and a separate WordPress plugin that allows data to be interchanged between the two installations.
Additionally, cross-posting and user accounts synchronization is also supported, along with multiple WordPress sidebar widgets.
In our tests, WP-United behaved wonderfully and we got it to work without any errors or having to go through a complicated installation process. This is why we gave it our “Editor's Pick” award and we heartily recommend it to anybody that doesn't want to give up on phpBB3 for bbPress just to be able to use the WordPress platform for their site.
The WordPress plugin is available on the official WordPress plugin repository, making it easier to install via WP's built-in plugin installation tool. There's a mod development thread on the official phpBB3 Modifications Forum as well.
