Clone this article

Question

Today I was looking my article 

Getting Started with Razor View Engine in MVC 3

OR

http://www.c-sharpcorner.com/UploadFile/3d39b4/getting-started-with-razor-view-engine-in-mvc-3/

I find that my article has extra image button for "Clone this article". When I clicked I got message article is cloned in red (red represents error in some sites ) so I thought that I did something wrong.

I went into My Account panel and find a link of cloned article where find same article .

Can anybody please explain this new feature of C# Corner?

Thanks,

Sandeep
