XBL Public in Halo 3? Where is it?

One of the first things my brother and I looked for upon returning home with Halo 3 in hand was the XBL Public feature and settings.  But it wasn't included in Halo 3!  I guess a petition has been started at Bungie to include it and there's an article up on digg.com

Here's the article about XBL Public.
