Flex pureMVC MySQL PHP test

This is a test to evaluate your programming skills using these tools for real projects.
The goal is to create a sample flex application using pureMVC.
It must allow a user to create a new account, validating username, email and password strength before submitting, activate this account via mail, login and edit his data in a form.
No fancy designs, just plain flex forms.
That's all.

server: LAMP + webORB
user table: username, email, password (md5 encription), first_name, last_name, birth_date
