User page vs sandbox
Hi. You seem to be using your user page as a sandbox. You already have your own sandbox for experimentation. We have guidance on what user pages should or should not contain. Your user page is ideally where you tell other editors about yourself. Furthermore, you have recreated 32nd Army Air & Missile Defense Command on your user page and making edits to your copy. You are free to make changes to the actual article, where you can interact with other editors working on that page. Please ask if you have any questions.

 * Hi, I am new to wikipeida, I already used up my sandbox since I already edited one article. How to add an additional sandbox? — Preceding unsigned comment added by Yachenzhang (talk • contribs) 14:17, 8 March 2014 (UTC)
