It’s a bit technical and not many people may be too interested, but the new set up on MCS is all the Spaces feed content to the front page through what I’m calling “Notifier posts” that have no attachments and have an association back to the Space post.  Now when you land on one of those Notifier posts you’ll be automatically redirected to the Space post.  Key points of interest are that comments are disabled on the Notifier post and comments are enabled on the Space post.  Ratings go on the Space post and not the notifier, though I’m still struggling to figure out how to show the Space ratings on the Notifier.  Till I do, just click through to the Space post to leave a comment or rating!
