Indeed, for a proxy this is relatively well concealed, but at the same time hopelessly overloaded. This might just be my personal preference, but you could benefit from a cleaner template.
I don't think that the majority of your users is reading the explanation of what a proxy is, what it can do and why they even exist.
At the same time, i find the "Personal Info" box to be the best feature of your site. Why not bringing the proxy address bar right below it?
*********Personal Info************
****Tag Line to introduce the proxy***
*********Proxy address bar********
The content could be brought behind a tab, "Info about Proxy". If someone is really interested to find out what it is, they can go there to read it.
If you could clean up the template and add a Favicon and re-arrange, you should be fine.
