Welcome to Wikipedia. Although everyone is welcome to contribute to the encyclopedia, one or more of the external links you added 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. Sole Soul (talk) 20:01, 29 November 2009 (UTC)

Hello Ldemasi. Thank you for taking an interest in our article Lift-induced drag. I notice you have added a lot of new material but you haven't identified the source of your information.

See WP:Verifiability. Information that is not supported by sufficient in-line citations to allow independent verification is regarded as no better than original research and can be deleted. (See No original research.)

Please add in-line citations to support your new text. For guidance on how to add in-line citations see WP:Citing sources and WP:REFBEGIN. Dolphin ( t ) 05:23, 25 January 2014 (UTC)
