When you click in the username of someone in this place:
It doesnt go to the profile of that user but to the profile of the last user replying to the topic ( which is the same if you are seeing an updated version of the page ).
I discovered this because i was looking at a cached version of T&T and when clicked on my username to see my profile in a palce like that, it went to Killov's profile because he was the one who had replied at last.
I dont think this is a big trouble but blah
