I'm glad to see this up and running.
The fact is that most of the "binding" portions of this treaty were already part of our individual alliance's mindset and rules for example "don't poison the well by raiding your home sphere". The important point behind all of us coming together to sign this is to show the world that although we may not be one big happy family we can respect each other and not play petty games. I don't expect iFOK to invite SNAFU over to Festivus dinner but there's no reason we can't work together on a trade circle and perhaps share a joke around the water cooler of the new PoP headquarters.
That being said, even those purple nations who are not members of signatory alliances should visit our centralized trade and economic forums, [url=http://www.prosperityonpurple.webege.com/smf_1-1-11_install/index.php]PoP[/url] and see that there's still plenty of love to go around on the purple sphere.
