Okay, I know this is just going to piss you off in all likelihood, but it's best to be certain. That's 'it's' as in it is. Not 'its' as in possessive. And in the 'Why?' pop-up (http://www.nationstates.net/pages/why_email.html) about supplying an email when registering a nation, you have used 'it's' instead of 'its', referring to NSII as the sequel to NS.
