ZIP File - http://www.phpindex.com/projets/projets_telecharger.php3?projet_nom=phpFAQTory/phpfaqtory_v1.4RC1.zip
Gzipped Tarball - http://www.phpindex.com/projets/projets_telecharger.php3?projet_nom=phpFAQTory/phpfaqtory_v1.4RC1.tar.gz

www.perldesk.com has a good KB and faq manager built into it's helpdesk software.

KBase is absolutely excellent. It's not quite free, but it's well worth the investment.
