I'm planning on adding a forum to my price comparison site for customers to discuss their products. Does anyone know of free a forum (PHP) that uses search engine friendly URLs (such as this one)?
There's a free mod available for PHPBBthat uses mod_rewrite to make the URLs search friendly.
There's also one for vbulletin, but that costs money :)
I think pretty much all the popular forum scripts are configurable to have search engine friendly URLs - it would certainly be a frequently requested feature.
There's Drupal (which powers this site), although that's more of a CMS than just a forum system. Another popular one is phpBB.
Cheers,
David.
