Orca is a groundbreaking forum system designed for Web 2.0, incorporating AJAX technology. The standout feature of Orca is its unique approach to administration, empowering users to manage the community themselves. Unlike traditional forums, there's no need for a designated administrator as users can collectively handle post and message management through a voting system that determines the significance and popularity of each post.

Moreover, Orca offers seamless integration with feed readers through RSS syndication, enabling users to easily follow discussions. Additionally, setting up Orca is a breeze, as it operates similarly to most contemporary database management systems, ensuring a smooth installation process.
