Do you know Tandem?

Folks, I found this amazing site for learning languages ​​online.

It is a new website that brings together people who want to learn a particular language. These people are called "tandem partners." For example, a Brazilian who wants to learn English could form a partnership with an American who wants to learn Portuguese, and so on. This "tandem partnership" can be live (if people live in the same city) or through skype/online. It's great! The focus is often in conversation, but people can also focus on anything they want - writing, reading, translation of documents and so on. I'm loving it. And the best part is it's completely FREE. Really, really good. I'm learning Japanese, Chinese and Korean, and I'm starting a partnership with someone who will help me with my Chinese. If someone elase uses it, please tell here your impressions.

Hello Ghani....The site sounds great. Please provide me its link. A friend of mine is looking for a site just like it, he wants to learn Japanese. I think we can help him out.
