I am researching the integration of phpBB into WordPress. I will put the results of my research here as time goes on.
Wp2BB Plugin Home Page – Wp2BB in the WordPress plugin directory – The homepage has phpBB set up very well stylistically – It creates a forum topic automatically for every entry in your blog if you want.
You have to install your phpBB separately. Appears that it does not integrate USER / PASSWORD authentication. What that means is to log into the blog you have one user / password pair and yet another pair for the bulletin board software.
Appears that the USER / PASSWORD integration problem was solved in this case. I have not tested this but did read on their site that it is integrated.
BBPress is not phpBB. It is by the WordPress crew. For this reason I suspect it integrates more easily.
bbPress Integration – This plugin gives the default WP role to users who registered through approved bbPress installations. It also populates things like usernicename and displayname as necessary.
Notes on bbpress installation:
I found that in spite of having the most up to date version of WordPress I needed to add the following lines to my wp-config.php file
define(‘LOGGED_IN_KEY’, ‘KeyValue3’); AUTH_KEY, SECURE_AUTH_KEY, LOGGED_IN_KEY explanation here HOWTO: Set up secret keys in WordPress 2.6
define(‘SECRET_KEY’, ‘KeyValue4’); Secret Key Explanation here
The respective key values are long strings of random characters.
