Chris is right. If I'm not mistaken, you have to be the profile manager, not just on the trusted list, to approve trusted list requests. (On the other hand, you should be able to directly add someone to the trusted list, if you have their email address. That can be done on the Privacy tab.)
You got the email because it went out to all Quebecois Project members. But only the Quebecois Project account can actually act on that email.
