HI there!
We are not able to learn from through the virtual medium like the net per se; but this is how you can keep your language alive by meeting other like minded people on the net.
Keeping your language alive is very important; teachers and listening to music will not be enough. You have constantly retrain the brain and improve your ways of learning; mechanics have to be changed to suit the language you want to learn.
I invite you to learn with me; check out my profile.
