If you’re like me, you like the idea of forums and bulletin boards, but they too often get way to crowded and clutter, and they look awful most of the time. Now I’ve found two alternatives that look good.
Vanilla is an open-source, standards-compliant, multi-lingual, fully extensible discussion forum for the web. Anyone who has web-space that meets the requirements can download and use Vanilla for free! via http://getvanilla.com/
bbPress is forum software with a twist from the creators of WordPress.
Have you ever been frustrated with forum or bulletin board software that was slow, bloated and always got your server hacked?
bbPress is focused on web standards, ease of use, ease of integration, and speed. We’re focused on keeping things as small and light as possible while still allowing for great add on features through our extensive plugin system. via http://bbpress.org/
