I am unable to create a public account. I get a spinning wheel when I input a public name, and it doesn't do anything else. The create button is disabled until (seemingly) I get a response back telling me my chosen name is okay or not. Unfortunately, their Web site didn't seem to have any clear way to register an account. Another point is that searching for contacts only works if you type in their last name. If you try searching for a contact by first name, then they won't show up.
