This is not there anymore, not that I have seen: "ok way 1: type their name into the member search, go to their profile, to feedback and over to the right of screen is the link to leave feedback."
The #2 option is what it was changed to: " way 2: if you see their name in a thread, you can click on their feedback score and you will be taken directly to the feedback page, again over to the right is the feedback link."
