Hello, I'm Materialscientist. I noticed that you recently removed some content without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Materialscientist ( talk) 06:02, 13 November 2012 (UTC) reply

Please do not add inappropriate external links to Wikipedia, as you did to List of U.S. minimum wages with this edit. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate may 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. Jim1138 ( talk) 07:51, 13 November 2012 (UTC) reply
