I like Universal Subtitles website.

Logo of Universal Subtitles
I recently discovered the site http://universalsubtitles.org which is a gateway to online video material and allows us to subtitle online videos. In the past I tried to do something similar with http://mycaptions.org (offline) with an arcane editor using BUedit. With that system I managed to add subtitles to this video of which I like the animal.
