What it makes Welcome to Wikipedia. We invite everyone to contribute constructively to the encyclopedia. However, the external links you added do not comply with our guidelines for external links. Wikipedia is not a mere directory of links; nor should it be used for advertising or promotion. Since Wikipedia uses nofollow tags, external links do not alter search engine rankings. If you feel the link should be added to the article, then please discuss it on the article's talk page before reinserting it. Please take a look at the welcome page to learn more about contributing to this encyclopedia. DGG 09:44, 3 April 2007 (UTC)
