On this site you can see all your specific stats from every time you've played ut3. The search for name system doesn't really work, but I used Google with this: UT3 + Stats + (name).
Update: Due to the closure of GameSpy, the in-game friendlist/messages etc don't work anymore, but also the gaming stats have been frozen. Everyone is ranked 1000 now and the provided link will show you a cached version of the stats.
