I asked myself that question many times, what is the best forum to add to his blog on Wordpress. Well I will not install on all my personal blog to give you the opportunity to see what is the best but I'll tell you what I think just share my experience on each of them except one Only it seems.

They are five in number, all plugins to enable:

• Wp-forum - Example
• BBPress - Example
• Simple Forum - Example
• Xdforum - Example
• RsDiscuss (The one I have not tested) - Example

D'ore already and I for one simple forum seems to be the best forum available to date for wordpress. It can resume without problem using the database of members of your blog. URL rewriting does not seem yet implemented a shame, because it remains a black spot in terms of readability and SEO. The use of avatar (plugin gravatar2 or imported image) to illustrate your words is possible. The French language is also available and has been translated by Lawrence Carroll, thanks to him. You will find a very detailed description of this plugin forum is strangely little about him compared to others. functionalities Simple Forum

My second choice would be rather then XdForum which now has several developers who improve and compatibility with older versions of Wordpress is still guaranteed even if he strongly encourages users to migrate faster in 2.x. For those who appreciate the url rewriting, Xdforum supports it in its latest version and it works pretty well. 3 types of text editors are available Quicktags, Smarty, FCKeditor. He also joined the membership base and can manage user profiles from the website. The avatars are also present. The team is still seeking a translator for the French version uses the same system with the wordpress files and Mo Po

BBPress now is in turn supported by the developers of Wordpress and not necessarily that, it weighs in the balance. We like its simplicity of use, system tag, the ability to view all unanswered, unresolved issues. You can also view a detailed profile of a user and the latest subjects in which he participated. The administration interface provides statistics allows to declare or moderators alias Bozo spammers. Finally, a feature many forums lack is one that allows you to add a topic in a favorite list.
I have not tested the version of WP-Forum, so if there are opinions on the latter, they are welcome.
