Flock integration or Flock integrates with xenForo. The Flock browser been around for awhile, I'd say by far the best social networking integrated browser to date (August 6th, 2010). http://www.flock.com I use: IE(5.1-8), FF, Opera, Chrome, Safari, and Flock on a daily basis and Flock has the best social networking benefit. Only downside is that it takes a few seconds to load, but a lot less time than IE9. Anyways, this isn't a big deal, but something to tuck away for future reference.
