Please do not add commercial links or links to your own private websites to Wikipedia, as you did in 5S. Wikipedia is not a vehicle for advertising or a mere collection of external links. You are, however, encouraged to add content instead of links as long as the content abides by our policies and guidelines. If you feel the link should be added to the article, then please discuss it on the article's talk page rather than re-adding it. See the welcome page if you would like to learn more about contributing to our encyclopedia. Thanks.
