Remove myself as a reviewer

Great product, I love it. Unfortunately I am a reviewer for some stale Code Collaborator reviews. I am tired of seeing mention of them and I cannot get the author to cancel the review. So, how do I go about removing myself as a reviewer? I know how to change from reviewer to observer and vice versa but I wanna' dissapear form the review altogether. We are using ver 7.3.7304. If this is not possible, well then there is a feature request.
