10 Wikipedia rules:

1. Neutrality: All sides of an issue must be presented with equally important supportive evidence (if available).

2. Civility: Don't use wikipedia to prove a point or pursue an agenda. Politely edit pages. Don't use it as a forum for opinion.

3. Consider the other editors when making an edit. Take into consideration the previous posts and their relevancy.

4. Avoid irrelevancy, only include information that is pertinent to the topic.

5. Refer to the talk page and the edit history before making an edit.

6. Information supported by previous research.

7. Sources should be cited and should originate from reputable places.

8. Don't recklessly change the titles of articles.

9. Don't recklessly create new articles.

10. Often small changes and minor edits are better than completely new creations.
