This paper describes a Web-based application, the PCS-Tool, which can be used for carrying out online peer review. The tool makes it easy to bring together communities of learners from all walks of life for purposes of sharing their written work and receiving feedback on it. In this completely learner-centered environment, writers are able to gain confidence about their written texts before they turn them in for the critical judgment of, for example, a teacher, publisher, or group. By taking away the focus on a teacher as the only evaluator of one?s texts and opening the way for peer-to-peer feedback, a door is opened for life-long learners.
