[ASK] How to build forum site?

My difficulty in building a website forum using wordpress, is there a plugin that is used to build a forum in wordpress? any idea??

 

you may want to try http://bbpress.org/
Its developed by WordPress creators.

You can also try http://wordpress.org/extend/plugins/zingiri-forum/ wordpress forum plugin.

 

you can launch bbpress like wordpress.org

 

is that pugin forum like bbpress and zingiri forum work well for any themes in wordpress?? which one plugin better you choose?

 

Simple Press is what you need: http://simple-press.com/ with a forum look and you can control it within your dashboard. Else, use BBpress http://bbpress.org/ on subdomain and use BBpress integration plugin: http://wordpress.org/extend/plugins/bbpress-integration/

 

using some CMS such as PHPBB.
