I tried to begin a discussion in one of my Nations and it's not available. Why?
The author or seeder of the content you're trying to begin a discussion on has blocked the Nation.
The “Start a Conversation” “Choose A Nation” menu will not contain any of your Blocked Nations. You will see this message:
If you're trying to comment on a seed, you can re-seed the article in your own column order to comment in the Nation.
