If you copy a page from Wikipedia
or any other source under CC-BY-SA license, add the template {{Source Wikipedia}} (in wikicode) at the bottom of the article. This will display a link to the corresponding article un Wikipedia. Please do that in order to respect the license CC-BY-SA.
This rule doesn't apply to modules/templates/categories for which a link is automatically displayed.
Everybodywiki doesn't want to create duplicate with Wikipedia, so you can copy articles from Wikipedia (which are not considerd for deletion) only if you are planning to fork (rewrite) it enough to be interresting for users and not considered as duplicate content by search engines
