Wiki-mandments

1. Thou shalt keep thy opinions to thyself. (Wikipedia content is intended to be factual, notable, verifiable with external sources, and neutrally presented, with external sources cited.)

2. Thou shalt watch over thy neighbor. (Intentional vandalism can be reported and corrected by anyone.)

3. Thou shalt not be bias. (All Wikipedia articles and other encyclopedic content must be written from a neutral point of view (NPOV), representing fairly, and as far as possible without bias, all significant views that have been published by reliable sources.)

4. None shall be turned away. (Anyone can contribute to Wikipedia by clicking on the Edit this page tab in an article. Before beginning to contribute however, you should check out some handy helping tools such as the tutorial and the policies and guidelines, as well as our welcome page.)

5. Thou shalt not be cheap, go buy a dictionary. (Wikipedia is not a dictionary, usage or jargon guide.)

6. Thou shalt not publish your work here. (Primary (original) research such as proposing theories and solutions, original ideas, defining terms, coining new words, etcetera. If you have done primary research on a topic, publish your results in other venues such as peer-reviewed journals, other printed forms, or respected online sites, and Wikipedia will report about your work once it becomes part of accepted knowledge.)

7. Thou shalt not rant. (Wikipedia is not a soapbox, a battleground, or a vehicle for propaganda and advertising. This applies to articles, categories, templates, talk page discussions, and user pages.)

8. Thou shalt not customized your own page for your friends to read. (Wikipedia is not a social network such as MySpace or Facebook. You may not host your own website, blog, or wiki at Wikipedia.)

9. Thou shalt develop a thick skin. (Wikipedia may contain content that some readers consider objectionable or offensive. Anyone reading Wikipedia can edit an article and the changes are displayed instantaneously without any checking to ensure appropriateness, so Wikipedia cannot guarantee that articles or images are tasteful to all users or adhere to specific social or religious norms or requirements.)

10. Thou shalt not "How-to". (Wikipedia is an encyclopedic reference, not an instruction manual, guidebook or textbook. Wikipedia articles should not read like an instruction manual.)
