I posted this link not for the app (I don’t know how Moof is yet) but to notice you about a really nice (for me) kind of usage of form!
On the bottom of the page you can see the form to sign up, I think it’s a great example of how a sign up form can be creative and elegant!
I have just a doubt … everyone will understand that it’s a form to sign up? I did … but the basic internet user?
Anyway I really like it!
