We've updated the site today. We've made a few changes to the UI and are still working out the kinks. You'll notice that we can now take blog comments, and there's a new link up top for "forums" (of which there is only one at the moment). We do require a LiveID Sign In to comment or to post in the forums. Let us know how that goes. It was a little confusing for me, but then I log in with several different accounts.
