Be civil. No personal attacks. Do not get defensive. If there is a problem, message the admin.
Stay on topic. Most of these threads read by busy people, so please pay attention to the topic of your messages, and check that it still relates to the topic of the thread to which you are posting. Off-topic discussion not taken to private email or private message if you wish.
Be kind to newcomers. Newcomers may ask the wrong questions, including ones that seem obvious (or whose answers seem easy to find). But lots of valued contributors started out this way, and treating newcomers kindly makes them more likely to turn into the valuable community members we all know and love (and cut some slack when they mess up).
Point newcomers in the right direction in addition to turning them away from the wrong ones, and be kind to them in the process of correcting their transgressions.
Let sleeping dogs lie. It's tempting to revisit controversial decisions you disagree with, but it's rarely productive to do so, since it almost always results in the same heated, lengthy, and time/energy draining discussions leading to the same conclusion that was reached in the last round.
Therefore, for issues already raised, discussed, and decided upon, reopen the discussion only if you have significant new information that would reasonably prompt reconsideration of the original decision.
