PHP Sign up/Login

I had originally wanted to include a members area where users could store their mixtapes they had made. I coded up a sign up form and login script for this.

There was no design and it was still in its early stages. It still would have benfitted from:

1. Adding a $_SESSION variable for the username
2. Error messages to display for individual fields which are missed within the sign up/login stages
3. A second "reconfirm" password for sign up
4. To include MD5 encryption
5. To include cookies for when a user close the browser and the session closes
