Forums are powerful platforms for user generated contents and there by increases the traffic to websites. So many bloggers have started their own forums. We have several tools available to integrate forums with wordpress blogs. But sometimes it is very hard to tweak the forum templates with respect to the blogs. I feel Wp-united is a powerful tool which integrates phpBB3 and WordPress 2.3.x. The configurations are simple and easy to follow.
All installation steps are explained in the install.xml file in the wp- united package. Initially you have to upload the wp-united files to corresponding location as specified. After that you have to tweak some phpBB forum files. I provide you phpbb3 files that has been tweaked for wp-united integration, hence you can directly upload them to the specified location. It will make you one step easier . Then logon to forum control panel after running wpu-install.php in the root folder of the wp-united package(Upload it to the root folder and call the url to this file) and there will be a wp-united tab which will lead you to the configuration process.
