oh thank you for telling us! i changed it.
edit: i also added some infos about the nico Q version, just in case.
No problem.
I looked at your update and it isn't clear that the English version can be accessed via nicovideo.jp. Could you update that?
Also, their name changed from ニコニコ動画 to just niconico back in June of last year as they're trying to get away from just being a video site. Concurrently, the English name of the service is Niconico. They also spell it that way on their Facebook page: http://www.facebook.com/niconicocom
