Welcome to Wikipedia. Everyone is welcome to contribute constructively to the encyclopedia. However, please do not add promotional material to articles or other Wikipedia pages, as you did to Wikipedia_talk:Signatures. Advertising and using Wikipedia as a "soapbox" is strongly discouraged. Take a look at the welcome page to learn more about Wikipedia. In addition, the comment you made had nothing to do with the subject of the page to which you added it. Please refrain from adding information in inappropriate places: if this continues it may lead to your being blocked from editing. JamesBWatson (talk) 09:53, 30 July 2009 (UTC)
