VK.

Before all, let me recommend you one good book about my belowed country.It's a bit expensive, but you can get used ones for 7 $ or so .

Now about VK. It's something like Facebook in Russian-speaking countries. It's a good way to learn Slavian languages and meet some friends from the East. I was surprised- just few days after I've created my account, a lot of people wrote me, offering their help with learning Belarussian.

Above you can see the top of the page in Belarussian (tarashkievica! Yeah, I was so happy to find this one among numerous languages accesibles). Anyway, you can also choose another language, like English, Russian, French...

Enjoy!
