How do you set up moderated groups?

Posts from new contributors or new threads go through the moderators for approval first ("hand moderation"). Posts to existing threads from experienced contributors are automatically allowed through by computer. Discussion threads on particularly heated subjects (usually politics) are continuously hand moderated to prevent flame wars from occurring, and if they do, the thread can be shut down. The system is not perfect: posts can be lost and the group can be down to new posts if the moderation computers are being moved or during power outages, etc. Appearance of new threads are dependent on the availability of the moderators, and may sometimes take more than a day to appear. Occasionally, complaints of censorship arise, though these complaints are often from people who were making posts that violated the clearly set rules. Nevertheless, the forum is still a popular discussion ground for Straczynski's fans, with the main selling point being the opportunity to interact with Straczynski.
