multisite register in one single page, like 'edublogs'

Hi everybody.

I’m trying to reduce the register process to users that create new blogs, like in EduBlogs.

inn EduBlogs you choose username, and the password, then the url and the title in the same page.

I already have installed multisite.

My problem is with the wp-signup.php

In EduBLogs the register process occurs in one single page. But in the wordpress the register process takes you in two pages before it is complete.

In EduBlogs you just choose all the options (username, email, password, url) and it’s done

In WordPress first you choose username and password, then you go to a second page to choose the URL and site name.

Any help will be appreciated.
