Courtesy: You have the right to speak, and also, you are obliged not to interrupt others. Speaking without being recognized by the moderators is strongly discouraged. Moderators will remove such people.
No Ad Hominem: We know you don't always hear ideas you like; in fact, you would likely encounter ideas that offend you. When that happens, we ask you to direct your criticism against the ideas, not the person.
Stay on Topic: Sometimes it is tempting to wander from one topic to another. When that happens, we will be forced ask you to refocus.
