I have a website in which comments need to be approved. Anyone can comment since I'm not providing registrations.

I'd like to have comments approved from the front-end. Form etc. is working and available - however only the main admin can approve comments. I've set up another account with different username/password but same group as Super User, but they can only see approved comments (so cannot approved those that are still unpublished) - this in the frontend.

Have I missed any settings or something?
