No it really doesn't seem intuitive, especially since the instructions given don't work (at least for me). The only way I have been able to make it work is to click on where is says "Feedback Score: # (%)" right under the member's avatar on a post in a thread. If I click on that number it takes me to the Feedback page for that member. Then on that page I get the link to post feedback (it is in the right hand column). Good Luck!
