Welcome to Wikipedia. Everyone is welcome to contribute to the encyclopedia, but when you add content (particularly if you change facts and figures), as you have to the article Scientology and celebrities, please cite a reliable source for the content you're adding or changing. This helps maintain our policy of verifiability. Take a look at Citing sources for information about how to cite sources and the welcome page to learn more about contributing to this encyclopedia. Thank you. Cirt (talk) 00:27, 10 November 2009 (UTC)

Please do not add non-notable names to the list of birthdays or deaths. Only names that have corresponding Wikipedia articles are eligible for the list. Your edits appear to be vandalism and have been reverted. Thank you. -- Mufka (u) (t) (c) 20:49, 2 August 2010 (UTC)

Please stop adding unsourced content, as you did to Nigel de Jong. This contravenes Wikipedia's policy on verifiability. If you continue to do so, you may be blocked from editing Wikipedia. Mattythewhite (talk) 16:25, 7 November 2015 (UTC)
