This plugin is under heavy development. Please do not use it in production unless your willing to accept difficulty of 
upgrading or correctness of the conversion.
ForumConverter migrates post, topics, and users from one forum to a WordPress compatible forum. Currently, 
ForumConverter supports phpBB 3.0.9 to bbPress 2.0 conversion in addition to migrating users as subscribers 
to your WordPress blog.
ForumConverter migrates users from the source forum database to WordPress compatible forum so that migraters can take 
advantage of BuddyPress social networking. This is not a bridge.
For phpBB-to-bbPress conversions, ForumConverter is capable of…
<ul>
<li>reproducing the same forum tree structure for bbPress</li>
<li>reproducing forum post using the same same user, timestamps, sticky flag</li>
<li>allowing converted users to sign on using their existing phpBB password.</li>
<li>converting between BBCode or native bbPress HTML markup</li>
<li>supporting inline attachment conversion and whole topic/reply attachment conversion.</li>
<li>migrating of instant messenger info, global moderator membership, and emails.</li>
<li>password protected forums migration using the same phpBB password</li>
</ul>
Some things that are impossible to do for ForumConverter for phpBB-to-bbPress conversions
<ul>
<li>Complete conversion of custom BBCode. Only YouTube BBCode is supported but BBCode lite does not support YouTube tags. </li>
</ul>
Please read the installation instructions before preceeding. Remote conversion is not supported.

Bridge phpBB and WordPress!
WP-United glues together WordPress sites and phpBB forums. Get the full power of WordPress publishing and plugins, with the familiar and established community format of phpBB.
WP-United is fully modular and individual features can be turned on and off. These features include:
<ul>
<li>User integration: including single sign-on, synchronised profiles and avatars, and user management. Works with external registration modules such as social login plugins. Users in phpBB get accounts in WordPress and vice versa. Completely controllable and customisable by setting permissions for who can integrate and at what level, using a unique drag-and-drop interface.</li>
<li>Template integration: Have your phpBB forum appear inside your WordPress site. Or vice-versa; integrate your WordPress blog inside your phpBB header and footer. Includes a “one-click” mode that analyses your theme’s CSS and modifies it on the fly to avoid CSS and HTML conflicts. This is no iFrame solution, it is a complete and automatic template integration.</li>
<li>Behaviour integration: Use phpBB smilies and word censor features in WordPress </li>
<li>Cross-posting: Post something in WordPress and have it cross-posted to your forum — Automatically or manually, you choose! Once an item is cross-posted, comments in phpBB and WordPress can be set to sync up under the blog item too!</li>
</ul>
WP-United also includes TEN widgets for you to drop into your WordPress page. Each widget is configurable and displays a wealth of forum information to increase engagement on your site. All of these widgets work even with the above modules turned off. They are:
<ul>
<li>Latest forum posts</li>
<li>Latest forum topics</li>
<li>users online list</li>
<li>Forum statistics</li>
<li>An integrated login/meta/avatar/profile block</li>
<li>Birthday list</li>
<li>Quick poll (select from active phpBB polls in an ajax widget)</li>
<li>Useful forum links list</li>
<li>Forum top bar (with breadcrumbs that work in WordPress)</li>
<li>Forum bottom bar (to match the top bar!)</li>
