Updated Weekly, BO and /who has more uptodate stats.

yep.. i would say that.. but that guy answer every topic!!!

In game, you can look at your BO by right-clicking on him to see specific numbers of ships
sunk by that particular BO. You can also type /who nicoala to see someone's win/loss rate
(any user name works).

In the forums, from the menu on the left, go to Community and then Ranking to see
individual levels, ships sunk, win/loss, and a few other stats. I'm linking yours:
