OpenId is used throughout the web to identify yourself for sites such as blogs and comments. Now, you can use NationStates to do this. For the first time, you can prove to sites that you control a specific nation. Unfortunately, this is a bit of a technical feature to use. We only provide delegation so you'll need to link your nation to another OpenId account. If you have any questions, please post them in the technical forum, and we'll try to help.
YOU SHOULD STILL NEVER GIVE OUT YOUR NATIONSTATES PASSWORD TO ANYONE OR ENTER IT ON ANY SITE OTHER THAN NATIONSTATES.NET.
