Unsourced edits on articles
Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, adding content without citing a reliable source is not consistent with our policy of verifiability. Take a look at the welcome page to learn more about contributing to this encyclopedia. If you are familiar with Citing sources, please take this opportunity to add references to the article.

The above is a standard message. I didn't change or revert your contributions because I don't have time right now to review the changes. Other editors will probably change them to make them more neutral. In particular, the part about "more and more people think" should be attributed to a source because it looks like a personal opinion on what people think. Please notice that this is a friendly advice. Have a good editing. Cheers. --Enric Naval (talk) 05:48, 17 August 2008 (UTC)
