Abstract: The patent describes and claims methods and systems for hosting and administering a forum for adversarial discussion. The invention consists of the underlying concepts, rules, and features of a distributed software program for conducting online debates. These concepts, rules, and features create a forum and an online tool for enforcing focused, rational debate. Rules are enforced that prevent digression, noise over content, and non-substantive, unproductive participation. In one embodiment, the method of hosting a debate includes the step of accepting a first statement from a topic author. By submitting the first statement, the topic author is creating a topic structure, which represents the basis for a debate on a particular topic.
