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 encyclopaedia 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. It often helps to explain contentious changes on the article's talk page so that other editors can understand the edits you've made. Articles often go through rounds of Bold-Revert-Discuss to address difficult topics.

When interacting with other editors, please be civil. This means assuming good faith on talk pages and trying to reach consensus over any disagreements in a respectful and considerate way, without ignoring the positions and conclusions of others. Assume that other people's intentions are also 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.
Reaching consensus is a natural and inherent product of editing; generally someone edits a page, then everyone who reads it has an opportunity to leave the page as it is or change it. Being wp:reverted may feel a bit deflating initially, but don't worry! It is a normal 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.
