I create a new web site about “The Martial Arts” with Wordpress. I want to create a forum work with WordPress together. I remember WordPress team works on forum software. They called “BBPress“. I install BBPress and it is asked me some WordPress questions about config file, i set them and i have got forum integrated with WordPress. Users are same in forum and WordPress. I suggest you BBPress if you are using Wordpress and want basic forum. BBPress is better in SEO. It is always come with its own seo system like wordpress. Here is my forum >

Read Config File to install BB Press

define('AUTH_KEY', 'aaaaa');

define('SECURE_AUTH_KEY', 'bbbbb');

define('LOGGED_IN_KEY', 'ccccc');

define('NONCE_KEY', 'ddddd');
