Pincode Sign Up

Hello Dribbblers,
I'm glad to announce that I've been selected to represent @protopie in the middle east. As part of being the ambassador of this great tool, I need to create useful User interfaces and prototype them.
My first story will be about Pincode Sign up. I will be responsible for creating tutorials too.
So stay tuned for the first the first protopie tutorial, to learn how you can create a real pin code sign up/sign in with protopie.
