The popular Japanese video sharing site, Nico Nico Douga launched an English beta version of the popular website! For those who have established accounts on the original Japanese website, you can still use it to log on into the English beta site. Users can also create a new account or log in via their Facebook accounts.
Additionally, the website features the text "Join Premium," although the text is not a link. The user settings area provides a link for users to register for a premium membership, which takes the user to a page stating that they are still preparing the premium membership and will announce more details "soon."
To those who don't have the idea of the original Japanese website, if you are familiar with the Vocaloid and MAD videos found on YouTube, most of those videos came from that site.
