Revel: How do I share photos?

I'm new to Adobe Photoshop Revel. I understand this is where our pictures will be migrating. However, the sharing feature is very confusing. When I click on the "SHARE" it say my pictures are now shared.. but to whom? There is no link to have the people I want to see the pictures to go to. Please let me know how I can share the pictures to certain people in Revel.
