I'm trying to integrate a basic forum into a WordPress CMS setup. I've searched the forums and the web at large, and usually what I find is something too basic, such as instructions on how to make their templates look the same.
Instead of help creating templates, I need help integrating the user tables of WordPress and whatever forum software. By "integrate," I mean that when someone logs into WordPress, she also can make forum posts, etc., without having to log in again.
I've looked at doing this with PHPBB, for example, and given up, for this reason: instead of using a set of common functions to make user changes and the like, PHPBB basically makes direct MySQL queries spread throughout its code. In fact, there are over 100 such queries regarding the PHPBB user table. To make PHPBB users integrate with WordPress would involve some pretty serious hacking of PHPBB.
So has anybody had any success integrating an open-source forum application with the WordPress users?
