Getting the search functionality to show people who have responded to the thread in general is a bit trickier, and when this happens I want to do it right so you can do this multiple times -- ie see threads that both you and I have responded to.

You can do that currently -- just put another name in the search box. The "Chiarizio" link is just so you can enter your own name more easily.
