Getting along with others
Summary
Review what you've learned
Writing on Wikipedia is highly collaborative, therefore there are two good starting points for how to get along with other editors: Be bold, and be civil.
When editing, be bold! Most edits make the encyclopedia better, and any mistakes can always be reverted or corrected. If you see something that can be improved, improve it, and do not be overly concerned with breaking anything. If the change is in the spirit of improvement and makes sense to others, the odds are good that everything will turn out all right and the change will be kept. If not, it's easy for someone to change it back.
Being polite entails remaining civil and assuming good faith when interacting with others. Being civil requires participating in a respectful and considerate way, without ignoring the positions and conclusions of others. Assuming good faith means that we assume that other people's intentions are to improve the project, even if their editing style is unusual, doesn't fit in with all the rules, or doesn't fit in with one's own views. If criticism or modification is needed, discuss editors' actions, but avoid accusing others of harmful motives without clear evidence.
Editors typically reach consensus as a natural and inherent product of editing; generally someone makes a change or addition to a page, then everyone who reads it has an opportunity to leave the page as it is or change it. Being reverted may feel a bit deflating, but do not take offense, as it is a common step in finding consensus. If you have a disagreement or suggestion, express it on the talk page, and politely discuss the change until a consensus can be reached.
