Hi there. On July 1st, 2009, Jolt closed NationStates 2 and began redirecting all visitors to a different Jolt game.
Earlier, Jolt had announced they were taking NS2 down only to retool it, and would bring it back at some indefinite time in the future. But since they've now wiped the entire site, not even leaving a News page for updates, this seems unlikely.
I've therefore taken back the domain name. It is, unfortunately, beyond my power to restore the NS2 game: that code belongs to Jolt. But if you would like to return to the original NationStates, now proudly Jolt-free, we would love to have you.
