Guidelines
1. You can add land, a nation you own, or both
2. You can only add other people's nations or change them if you get their permission
3. Anyway can change the land, but have a reason if you're doing more than just adding on so that you can fit a nation.
4. No trolling, like making 1 pixel islands all over the map, or half the map, etc.
5. Borders are 2 pixels thick. Unless anyone has a better idea.
6. Keep your nations a resonable size
