I've created a ping list for the North American Union topic, but sometimes I'm pretty slow at posting ping lists to new threads when they pop up. (I have a life y'know...) If anyone would like to administer the ping list, let me know and I'll Freepmail it to you.
IMO, this topic is going to be BIG in the coming months and years, and right now most people don't have a clue that it exists.
