Pengu Yu, in case somebody above has failed to make it adequately
clear to you, nobody owns Wikipedia's articles and if you think there
is something wrong you are encouraged to change it--if someone
disagrees they'll either change it back or start a discussion on the
talk page.
See this editing guideline page and read it thoroughly up to but not
including the section "Non-article namespaces".

And be bold!
