I don't know if anyone else noticed but Jumpcut has recently announced that the site will officially shut down come June 15, 2009. Quoting the site:
After careful consideration, we will be officially closing the Jumpcut.com site on June 15, 2009. Therefore, we are no longer accepting new uploads. This was a difficult decision to make, but it's part of the ongoing prioritization efforts at Yahoo!
Very soon, we'll be releasing a software utility that will allow you to download the movies you created on Jumpcut to your computer. We'll send instructions to the email address on your Jumpcut account when the download utility is available.
Once you download your movies, you may choose to upload them to another site such as Flickr, which now allows video uploads. You can find out more here: http://flickr.com/explore/video
Thanks for your understanding and thanks for being a part of Jumpcut.

JumpCut is a video mixing site that allows users to remix videos already online or edit their own video with its unique interface. Yahoo acquired the site in September 2009 for an undisclosed amount.
