This is a really important feature, in my scenario I have different categories in competition and I cannot allow moderators to share visibility of pending posts.
Dear @codinghorror, having the opportunity of isolating moderation among categories is essential in all scenarios where you’re running a competition. For example in my case we’re evaluating Discourse to integrate it in a crowdfunding website. Every category is associated to a fundraising campaign and moderated by the campaign owners. We cannot allow the sharing of comments among possibly competitive players. This is is true for a lot of similar scenarios and neglecting this feature means preventing the adoption of this really cool platform on a huge bank of growing initiatives.
