Is there a critique photo facility within the Aperture forum?

As I am new to Aperture 3 and not a professional, I am unsure as to the quality of my photography. I obviously have a lot of which are poor and a feeling that some might be good, but that is my own personal and subjective view. In order to improve, I need to establish where my 'good' photos stand. I was wondering whether there was a facility, whereby you could send photos and obtain constructive advice on quality or not, and how to improve via editing. If someone knows of such a facility, I would be grateful if the could point me in the right direction.
