Blood type
Thank you for your contributions to the Blood type article. However, you did not identify a verifiable source for the changes you made to Korea statistics and the statistics you added for Japan. Verifiability is a core policy of Wikipedia. Please update your changes with a reference to the source from where the statistics were obtained. If you are not familiar with how to properly add a reference, leave the information on my talk page and I will assist. Thank you. -- Tcncv (talk) 02:48, 10 February 2009 (UTC)
