Primary Broadcaster: When you go to Websites > Site Settings, you will see a place there for specifying the “main” broadcaster. That determines what Facebook page, Twitter account, and who the main email auto-responses in your nation come from.
Currently there are meta image variables for the site, but not for individual pages. Since it's possible to change the meta image per page, it would be cool if there was a variable for that.

To have a nation display in both english and spanish we'd need not just a content mgmt tool for i18n, but also a way to create and organize templates into spanish and english, and a button to allow users to switch back and forth.
