how to show pro sites signup like edublog

1)I've installed the pro sites plug in but my sign up page ,but it still doesnt look like edublog it still like a normal default wordpress register format http://fy-team.com/shopper/wp-signup.php

2) Can I set the register page when user register as our member, and they do not need to choose blog name ,they user name can be as their blog name?

Thank you
