http://developers.facebook.com/blog/post/472/ Maybe it's obvious to you, but Here's what it says to add to my site Comment box: <div id="fb-root"></div> <script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script> <fb:comments href="YOUR_CANONICAL_URL"></fb:comments> HTML: Meta tags: <meta property="fb:app_id" content="{YOUR_APPLICATION_ID}"> <meta property="fb:admins" content="{YOUR_USER_ID}"> HTML: What I don't know: 1. What is YOUR_APPLICATION_ID, and how do I get it? 2. I believe YOUR_USER_ID means my real actual facebook profile ID, but I'm not 100% 3. I believe YOUR_CANONICAL_URL means http:// www dot ourspacer dot com, but I'm not 100% on this either. HELP!
