on your iTrader page
 

I get a message that says "on your iTrader page". ​Where do I find this page?

Just click the words "on your iTrader page" and it should take you to it.

if you do not have a link to the iTrader page as bibliostone pointed to, you can access any member's feedback page by clicking on the blue number after the words Feedback Score in the list of member information on the left side of the screen.
