Wikipedia:Tip of the day/December 10
Another policy we value highly is Wikiquette - please try to be nice to everyone, all of the time. Good natured collaboration keeps Wikipedia running smoothly and developing rapidly. It makes the Wikipedia community a nice place to be and it makes Wikipedia a fun place to volunteer. Personal attacks are not tolerated, and may result in those responsible being blocked. If you get into a conflict, remain calm and endeavor to resolve the dispute peacefully. Thank you.
