The Mixxer

Another great tool found on Web! Joe Dale published the link to a free learning platform for language students, called The Mixxer (designed by Todd Bryant). With the help of their database anybody can find a language partner for a language exchange. If you're a native speaker of English, for example, and you want to learn Slovenian :), you can find a Slovenian learner of English and than the two of you can have (Skype) conversations and improve your language in cosy, informal environment. Teachers can also find other classes interested in doing language exchanges with their students.
This really seems to be a very simple but highly rewarding on-line experience. Has anyone tried it?
