We've just added a Member list to the main website.
Principals can now see if there is a proxy in a particular country.
Proxies can see how many other proxies there are in their country, and judge the competition.
You can view the memberlist at http://www.buy-proxy.com/memberlist.php
Hopefully this helps people a little bit more. Let us know what you think, and if there are any changes we should make.
