Google has a form up for you to request to become a "User Experience Research" at services.google.com/inquiry/user_study. Google is "currently looking for Google Page Creator users to participate in a user study to improve our product."
So if you love Google, like to test things, and enjoy Page Creator, then fill out the form.
Regina of Google, posted this request in the Google Groups forum.
Just to let you know, filling out the survey doesn't guarantee you'll be contacted.
