I have to say I agree with the above sentiments. WordPress needs a COMPLETE forum that integrates seamlessly as a 1-click install.
Joomla has Agora, only 10 months old but pulling in crowds. Yes the default templates are ugly, but when version 3 comes out, the templates are going to rock!
BBpress is intimidating to newcomers to web-management. If it was the "integrated forum of choice" it should have the following features:-
* 1 click installation to install into WordPress
* Automatic integration into the default WordPress styles / themes, and sit under the template "header" nicely and sit inside the WordPress "wrap" properly
* Easy extra styling for "forum-only" components in a WYSIWYG fashion, such as blogger's easy template editing
* WordPress would have about 10 different "base templates" that are naked templates ready for integrated WordPress/forum WYSIWYG formatting, with clear template header install packages for newcomers. (Such as "this header ideally accepts images ABC wide and XYZ high" or "click here to enable wrapper side background images, which can be XYZ wide on the side views). With easy "point and click" editing like this, users would flock to WordPress and its forum in droves. (It might even put some of us designers out of work! Eeewwww, why am I suggesting this!!!)
*Joomla has a long way to go as far as the WYSIWYG editing, but the integrated forum "Agora" is gathering momentum. Non-technical people are too busy to basically learn what amounts to a new career.
