Editors should interact with each other in a respectful and civil manner.
Respect and be polite to your fellow Wikipedians, even when you disagree.
Apply Wikipedia etiquette, and avoid personal attacks. Find consensus, avoid edit wars, and remember that there are about four million articles on the English Wikipedia to work on and discuss.
Act in good faith, and never disrupt Wikipedia to illustrate a point.
Be open and welcoming, and assume good faith on the part of others.
When conflict arises, discuss details on the talk page, and if needed, follow the dispute resolution process.
