There are a lot of ways to learn English, and in my opinion, using Skype is the best one due to the fact that you can speak to people from other countries. You must have to add people for calling them. If you go to a summer camp for improving your English, there you can ask lot of people their Skype username. But in Skype you can also chat with people. Finally, I think that Skype is one of the best applications for computer and mobile phone that has existed. I hope that you'll enjoy it! (here you have Scott!)
