VK (Originally VKontakte, Russian: ВКонтакте, literally “in touch”) is the second largest social network service in Europe after Facebook. It is available in several languages, but particularly popular among Russian-speaking users around the world, especially in Russia, Ukraine, Azerbaijan, Kazakhstan, Moldova, Belarus, and Israel.
Like other social networks, VK allows users to message contacts publicly or privately, create groups, public pages and events, share and tag images, audio and video, and play browser-based games
