As you may have seen, ABC seem to be gearing up for a new ARG related to the OGR stuff that has been floating around for Comic-Con. In case this does indeed turn out to be a new ARG I've started work on a new part of the site that we will use to run the game.

This can also be accessed via the navigation menu at the top of the screen.
Note: If and when this is confirmed as being a new ARG we will be looking for some contributors to the site, so stay tuned.
