I've just been introduced to VoxSwap, a great way for those who are wanting to learn a language and connect with people who can teach you.
It doesn't matter if you are a student needing help to get better language grades, a former student who doesn't want to let their language skills go rusty or a business person needing to speak another language for work. VoxSwap's premise is to ensure you can talk to real people and offer one another pointers on how to excel in a language.
This is another example of the beneficial uses of social networking, an alternative to Facebook! Whereby you can actually do something useful and stimulating whilst socialising.
