The thing which makes LingoRank differ from the other sites is improving the skills with a well-known site: TED Talks.

Under the videos there are 'vocabulary' and 'difference and the speed of the speech' sections with these sections you can list your words and you can learn the level of the speech.
If you want to know who created this site and how can we connect with the creator you can see a section at the end of the page.
When you click on 'About Me' you can see the creator: Jesus.
I think, by listening TED talks helps studentsto learn new words and to upgrade their levels. When they listen on their own, they will have more self-confident and they will learn new and creative things.
