Social Media Helper?

I'm looking for a behavior that allows users to post their score on Facebook.  I've searched around and have seen references to a behavior called "Social Media Helper", but I can't seem to find it.  It doesn't seem to be included with version 2.2, and it's not listed in StencylForge.  Has it been deprecated?

If a behavior doesn't exist, does anybody have any custom code they'd be willing to share?  Or even a link to an article that explains posting to a wall from a game?
