How do I change or remove my name in icloud.com Photo stream webpage?

I've setup a public site photo stream on my iPhone and can view the web page fine. In top right, it lists my name on the page and I want to remove it or change it. Is their a way to do this? I've tried a few things such as changing it on icloud.com account and in my icloud settings on my iPhone 4.

I have iPad mini, Macbook (10.8) and iPhone 4 all able to see the photo stream.
