Do you want us to add ProjectPier to the Bitnami library? You can vote for it on our wishlist.
ProjectPier is a Free, Open-Source, self-hosted PHP application for managing tasks, projects and teams through an intuitive web interface. ProjectPier will help your organization communicate, collaborate and get things done Its function is similar to commercial groupware/project management products, but allows the freedom and scalability of self-hosting. Even better, it will always be free.
