Hello, ShiraQila, and welcome to Wikipedia! Thank you for helping us build a great free encyclopedia. We have five basic principles, but other than that, we advise that you be bold and edit. If you ever have any questions or need help, feel free to leave a message at the help desk, and other Wikipedia editors will be happy to assist you.
Thanks again and congratulations on becoming a Wikipedian!
P.S. New discussion threads for you will appear at the bottom of this page.
It seems to me that an article you worked on, Yūta Tamamori, may be copied from http://www.generasia.com/wiki/Tamamori_Yuta. It's entirely possible that I made a mistake, but I wanted to let you know because Wikipedia is strict about copying from other sites.
It's important that you edit the article and rewrite it in your own words, unless you're absolutely certain nothing in it is copied. If you're not sure how to fix the problem or have any questions, there are people at the help desk who are happy to assist you.
