You do. I do not have an account yet, but I am already visiting the site a few times daily for refreshment. I plan on emailing info@piccsy and see if i can convince them to give me a few invites. Will def. share then.
EDIT: Email daniel at piccsy dot com. He's the founder.
Try Wookmark. I see it kind of like this: Pinterest:YouTube::Wookmark:Vimeo. It's super clean and easy to use, and it has a paid version where you can save private images and start private groups. http://www.wookmark.com/
