Yes you are correct but to clarify an admin can approve a comment on their site but as a super admin I want to approve their initial posts (and a common place to locate them such as all new posts). Their comments and replies do not have to be approved by me. Hope this clarifies this.
OK I see that but not sure you're quite understanding what I want to do. As you said it's a multisite so as admin I want to approve every post that someone is making to their site (all sites) and would like to have an area to see the activity of recent posts so I can approve them or not.
