Welcome to Wikipedia. Although everyone is welcome to contribute to Wikipedia, at least one of your recent edits, such as the one you made to Mao Zedong, did not appear to be constructive and has been reverted or removed. Please use the sandbox for any test edits you would like to make, and read the welcome page to learn more about contributing constructively to this encyclopedia. Thank you.

Please refrain from making unconstructive edits to Wikipedia, as you did at Space Race. Your edits appear to constitute vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Wikipedia has a policy against vandalism-only accounts. JustinTime55 (talk) 18:31, 2 May 2011 (UTC)
