Comment notification

Hi, I have two WP1.5 setups – each for friends of mine. On each I am the super user, level 10 and my friend is an Author at level 9. The strange thing is comment moderation is set up the same on each system but on one I get notification of comments to moderate for all articles regarless of who the author is (which I don’t want) and on the other installation my friend gets the notification (preferred).

Any ideas what I might be doing wrong here?
