Note that you'll need to be an admin of at least one public Facebook Page in order to add content to your Flockler site. We never show your personal Facebook feed and posts or publish anything on your behalf to Facebook.
When you click the Facebook button in Newsroom for the first time, we will ask you to connect your personal Facebook account. If you do not see any content from your Facebook Page after connecting your account, follow these steps:
Make sure you are an admin of at least one public Facebook Page.
Reconnect your Facebook account on your Flockler profile. You can find your Flockler profile from the top right corner of editorial tools. Instructions here
Go back to the Content tab and click the Facebook button - you should now see your Facebook Page content and you can change the Page from the drop down (If you have more than one). Drag n drop content published by Admins (My posts) or your Fans (Posts by others) to the stream on the right.
