Why isn't there a game feature with which we can type in the name of our country's capital city? In general I think there should be more information to fill out of that nature.
I did a search to see if this had already been suggested and didn't find it, but sorry if this is redundant.
Look under capitals, national leaders, nation anthems, provinces, legislators, national mineral, High Chief Dogcatcher, or any of a hundred other suggested additions. It's been suggested many, many, many times before. It will not be implemented in NationStates, but perhaps something like that will be in NS2.
Why not create a nation page on NSwiki (http://ns.goobergunch.net/wiki/index.php/Main_Page)? You can add all those things plus as much more as you want. It's an unofficial site and not affiliated with NationStates, but lots of us use it to keep track of stuff we want other people to know. Have a look.
