You can view your complete Work History & Feedback is to click on any posting (active or closed) on your Jobs page then go to View Job Post> View Posting. If you go to Jobs> All Contracts, you can see feedback for each job individually and respond to it under Terms & Settings.
If you view any of your previous job posts (open or closed) and scroll down to the bottom, you'll see the "Client's Work History and Feedback" section, which shows the ratings you received *from* each freelancer, with a smaller line below showing what you gave *to* that freelancer. You can also see your overall client rating on the right-hand side.
I still cannot find the "Client's Work History and Feedback" section. Does it still exist? Are you sure those instructions are correct? Can you send a screenshot?
Just to confirm that Jennifer instruction are correct and they still exist.
If your experiencing any problems with this let me know, if private information are involved you can send me a PM(click on my name).
