I don't know if this is already done, so forgive me if it is, but putting the commercial awareness updates into a newsletter. Then having this emailed out every week or so would make it a bit more snazzy and official.
Also perhaps dividing the commercial awareness updates in the forums into sectors/ industries e.g. oil/energy resources, tech, financial services, international relations, trade. Then if people were applying to a firm that had particular focuses they could easily go and get a simple digest of some of the relevant things that had been going on. But obviously still keep the weekly updates together when they get initially posted.
