Welcome to Wikipedia. Although everyone is welcome to contribute to the encyclopedia, one or more of the external links you added to the page Maxwell's equations do not comply with our guidelines for external links and have been removed. Wikipedia is not a collection of links; nor should it be used as a platform for advertising or promotion, and doing so is contrary to the goals of this project. Because Wikipedia uses nofollow tags, external links do not alter search engine rankings. If you feel the link should be added to the article, 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. Thank you. JohnBlackburne wordsdeeds 08:48, 26 August 2010 (UTC)

Please do not add inappropriate external links to Wikipedia, as you did to Maxwell's equations. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include (but are not limited to) links to personal web sites, links to web sites with which you are affiliated, and links that attract visitors to a web site or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the article, please discuss it on the article's talk page rather than re-adding it. Thank you. JohnBlackburne wordsdeeds 10:47, 26 August 2010 (UTC)

I thionk the added link (then removed) is useful to allow reading of article about Maxwell's equations and (original) quaternionic form. DELTA Ingegneria
 * Please read External links for a guide to what external links are appropriate to an article, and Conflict of interest for information on adding links to your own websites or your own products. In general it is not appropriate to upload links to a commercial web site, or to upload links promoting your own work, both of which apply here. In addition an account such as yours, which seems to have been created only to add this link, is given less benefit of the doubt than an editor of long standing who has already contributed to many articles (although the policies apply to all editors).-- JohnBlackburne wordsdeeds 11:29, 26 August 2010 (UTC)
