Comments on profile page?

I was thrashing around trying to remember how to post feedback. Finally got that figured WHILE doing so

cudamike asked me in an unrelated thread "if I got the message" he sent. In thrashing around with the feedback thing, I noticed that he? had evidently left comments on my profile page? Hell I never go there didn't know it was possible. So what did he do? I'm guessing he went to my profile page where it says "type something? or whatever?
