vk is a more than a 100 million active users website

VK is the largest European social network with more than a 100 million active users. On the website, you could find people with whom you've studied, worked or met on vacation, learn more about people around you and make new friends, and stay in touch with loved ones.

It is available in several languages but popular particularly among Russian-speaking users around the world, especially in Russia, Ukraine, Azerbaijan, 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.

As of December 2012, VK has at least 195 million accounts. VK is ranked 25 in Alexa’s global Top 500 sites and is the second most visited website in Russia. In December 2012 VK had an average of 43 million daily users.]

From the website you could see profile, friends, photos, videos, music, messages, groups, news, bookmarks, and settings.

Messaging. VK Private Messages can be exchanged between groups of 2 to 30 people. An email address can also be specified as the recipient. Each message may contain up to 10 attachments: Photos, Videos, Audio Files, Maps (an embedded map with a manually placed marker) and Documents.

News. VK users can post on their profile walls, each post may contain up to 10 attachments – media files, maps and documents (see above). User mentions and hashtags are supported. In case of multiple photo-attachments the previews are automatically scaled and arranged in a magazine-style layout. The news feed can be switched between all news (default) and most interesting modes. The site features a news-recommendation engine, global real-time search and individual search for posts and comments on specific users' walls.

Communities. VK features two types of communities. Groups are better suited for decentralised communities (discussion-boards, wiki-style articles, editable by all members etc.). Public pages are a news feed oriented broadcasting tool for celebrities and businesses. The two types are largely interchangeable, the main difference being in the default settings.

Like buttons. VK like buttons for posts, comments, media and external sites operate in a different way from Facebook. Liked content doesn't get automatically pushed to the user's wall, but is saved in the (private) Favorites section instead. The user has to press a second 'share with friends' button to share an item on their wall.

Privacy. Users can control the availability of their content within the network and on the Internet. Blanket and granular privacy settings are available for pages and individual content.

Language. As of October 2012 the site features 3 official languages (English, Russian and Ukrainian) as well unofficial user-generated translations into 70 more languages. Advertisements are only shown in the Russian and Ukrainian versions.
Russian-speaking users can choose between the standard Russian version and two extras: a Soviet version and a Pre-Revolutionaryversion. Other than language tweaks (e.g. telegrams for messages and comrades for friends) these versions contain other easter eggs. For example, all private messages in the Soviet version have a stamp saying 'passed server censorship'. The pre-revolutionary version uses old-style Russian orthograp.
