Your edit of Kasparov article. edit

Dear Diophantus,

Please do not delete supported by reliable sources information. I mean the information about membership of Kasparov in National Security Advisory Council. Here is relevant page of its site in Google cache showing Kasparov in list of its Council memebers. Even if that page won't exist, you still cannot delete this information because it is supported by the news article from newspaper Vzglyad, which is relible source according to all Wikipedia policies. Please familiarize yourself with Help and Wikipedia polcies before editing. You should discuss your edits on talk page first, before any editing.Vlad fedorov 14:59, 15 April 2007 (UTC)Reply

Your edit of the Global Warming article edit

I reverted your change of the term "climate change" to "global warming" because it was inappropriate. I notice that you made similarly inappropriate changes to other Wikipedia articles -- you might want to think about not doing that, or at least not before discussing it first in that article's Talk page. -BC aka Callmebc 18:29, 2 September 2007 (UTC)Reply
