There are hundreds of open source projects ranging from simple email software to publicly dedicated WWW servers and full operating systems. This article describes an online platform for educators with free open source educational systems including wikis, blogs, bulletin boards, Content/Course Management Systems, and MOOs, all open systems which are easily installed and managed. By setting up a content-based server, educators can save and archive their files online easily, and integrate their online resources without needing web design skill. With full control of these different educational tools, educators can form a collaborative learning community based on their teaching goals. Thus teachers and students can build an online community as partners. They can learn from and with others, share and try out web learning tools, distribute leadership and inspiration, and support and interact with others from all over the world.
