Turnoi, my friend,

Are you from eastern Europe, right ? ( from your own postings on this site ). PhDs could be easily bought there after the socialist era.
( 200 USD for one ). Therefore, it`s not surprising that a PhD-holder like you, makes so many writing and grammar mistakes.
As for Silverboy and Choatle, they are not teaching legally in China without a university degree. I expect important changes after the Olympics.
In 2004, tens of native speakers came to China from Japan and South Korea. They could be arrested and deported there for their on-line and fake degrees.
Turnoi, you are out of this business because you left China. Most of us don`t miss you at all !
