It's all streaming content (meaning you can't download it) but you can VIEW them, which is all that really matters. I'm guessing they are doing this so they don't get in trouble for "distributing" it like skramps. Anyways, its really new so there isn't a ton of stuff yet, but if you guys all upload then it can turn into something great. As far as I know they will not take copyrighted stuff, but who knows.
