How I can sharpen my english by Skype?
Is it possible?
I think it's good to join skypecasts and stay in the listening, so that you can pay attention to the way people really speak in a informal environment. You can learn some expressions of common usage. But I advise you that speaking in a skypecast full of english natives can be frustrating to both sides, so try to find a friend who wants to practice too.
