 **NOTE**: Before you can sync your community with the nation, you will need to create an additional dummy user on your community. Therefore, create one by clicking on "Become a Member" under the SIGN-IN button. Then fill out the details and press the "Become a Member" button. (Tip: When creating the dummy user, don't put a password that you actually use). Next, log back in to your admin account and double-check that your dummy account is listed under Members on the Manager page. Now that your community has a user, you can sync with the nation. If you can not create dummy user, please click on the helpful links and videos under the Useful Links section at the bottom of the Nation Planet page. Once there, scroll up to Q22 for a solution, which is located under the Technical questions section.
