FREE:
The website, since inception, has emphasized its no-cost policy. Therefore, everyone is eligible to use, edit, and share its contents. The premise for the free use of the content is assured as the editors have licensed their contributions to general use. Therefore, no editor owns a piece, even the ones they edited. It means that the articles are subjected to thousands of editing and use. Also, the website does not endorse plagiarism. Editors are instructed to respect copyright laws.
ETIQUETTE:
As a community with different people, Wikipedia has made it compulsory to treat each person with respect and civility at all times. Wikipedia’s are admonished to find a consensus and not engage in "edit combat" because of a disagreement. There are also dispute resolution procedures editors can follow if they cannot settle their conflict or ignore it. Every Wikipedia is admonished to treat new members well.
NO FIRM RULES:
Although Wikipedia has policies, they are not so static and rigid. It is more important for the editors to be self-regulatory based on the rules than to recite the policy's literal wordings. As you update articles, please do not beat yourself up for mistakes because they can easily be corrected. The policies are majorly behavioral guidelines in public places. The use of the reasoning of the editors is highly recommended.
