Please do not add content without citing verifiable and reliable sources, as you did to J. David Shapiro. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. Thank you. Cirt ( talk) 16:35, 30 December 2009 (UTC) reply

Please do not add unsourced or original content, as you did to J. David Shapiro. Doing so violates Wikipedia's verifiability policy. If you continue to do so, you will be blocked from editing Wikipedia. Cirt ( talk) 22:33, 9 February 2010 (UTC) reply
