I recently joined but it won't let me do anything but add vids to my favorites. Whenever I try to upload something it says there is an overload on their system and to try again later. That's been a week now. I can't even add a picture.Not all of them. The uploader can make it public, or restrict to "friends." There's a fair amount that's public (and so much stuff gets added each day, some of the private vids will end up getting shared later by others). That said, I've found it worthwhile to make an account and upload some of my fave vids in order to increase chances of getting access to the private vids.
