From the developers of WordPress comes bbPress, a new, light weight forum package that follows five key principles (as taken from their site):
> 1. Open Source, always and forever
> 2. Less (code) is more
> 3. Simplicity is a feature
> 4. Speed and security are the foundation of any good user experience
> 5. Put the user first
>
> Every line of code is written with these principles in mind..
bbPress can be seen in action in the WordPress Support area, so check that area out for a demonstration of what it can do. For those who have visited the WordPress Support area in the past, you will be pleased with the fact that the forums are much faster.
