How do people learn to be good digital citizens of avatar worlds?

The range of skills that a digital citizen needs to attain in order to function as a 'good citizen' within their chosen avatar world is a product of the possibilties offered by that world, and the guidance and communities of practice within that world. Good in-world guidance along with strong, actively fostered debate produces an environment where digital citizens are drawn into a culture of acceptable use by participation, mentoring, guidance, peer pressure and appropriate moderation. Real world values such as respect, tolerance, and good communication skills are all equally of value in-world, and possibilities clearly exist for translating good in-world citizenship into good real world citizenship and vice versa.
