Editing the Signup page and signup proceedure

I am trying to figure out where I would go to edit the information on the signup.php pages for the Pro Site theme.

Currently it is a two part form. After the form is submitted you are shown a message...

Congratulations! Your new site, the don of existence, is almost ready.

But, before you can start using your site, you must activate it.

Check your inbox at donlprivate@gmail.com and click the link given.

If you do not activate your site within two days, you will have to sign up again.

Still waiting for your email?

If you haven’t received your email yet, there are a number of things you can do:

Wait a little longer. Sometimes delivery of email can be delayed by processes outside of our control.
Check the junk or spam folder of your email client. Sometime emails wind up there by mistake.
Have you entered your email correctly? You have entered donlprivate@gmail.com, if it’s incorrect, you will not receive your email

Where do I go to edit that page. It seems to be generated automatically. Since there are obvious formatting issues I need to fix it.

In addition I would like to be able to have the user register all required information on the one signup.php page.

Damned if I can find it.
