Really 
This is the new comment system and forum at the same time. This has been developed in order to create a common place for all the Fab Lab to discuss together and not just about all the pages on Fablabs.io.
Oh I see, I just saw the “Start Discussion” link at the bottom of each Labs/Projects/Machines pages on .io. It makes sense now, and it’s pretty clever. It was just frightening to see it happen live, pushing all the latest discussions to the right of the main page into oblivion.
