== Oh, oh.. == 

 I'm living in multi-people house. There are my ten korean frineds who I told them to use Wikipedia. Well, they are also interested in korea stuffs. Since we all use apartment's router, virtually, it could be assumed that sockpuppet is suspected. My friend BBOPOPOS is knowing this, but other users do not know this since they are busy studying final semester test... 
 Sorry if you were suspecting me or my friends. ...Question: Are we able to play with our user page if frineds gave consents for testing or because of wrong informations?
