WP w3all phpBB for WordPress

WP w3all phpBB provides free user login and registration integration between a phpBB bulletin board and WordPress CMS.

Wp w3all phpBB integration Integration cookie based between WordPress and phpBB installed on same and subdomains.

After the setup and initialization of the plugin, WP users will automatically be added into phpBB when they register into WordPress (or in the case of old existent users, when they will login into WordPress), while without using the phpBB extension installed into phpBB, if users are allowed to register in phpBB, they will be added into WordPress when they will visit the WordPress side as logged in or at their first login in WordPress (or install the phpBB extension to add users at same time into WordPress when they register in phpBB). But you could use the plugin just only to transfer users between phpBB and WordPress by activating the plugin as not linked (read the help install page), or to show phpBB posts into a WordPress hosted into another domain
