Hello! Thank you for your article. I’d like to try to compare it to my previous experience of learning Portuguese through Skype on online classes. I did around 10 conversations over Skype with a native speaker from http://preply.com/en/portuguese-by-skype. And I was pretty satisfied with their Quality. I think they have a strong teaching quality. Following their course curriculum now I can speak Portuguese like a native. But I Want to try another option.
