For anyone else who is interested in the medals and ranks on the Metaverse, the Admiral rank has finally begun to appear. So far I have seen Shaman and SpinDoctor with this rank. It seems to be restricted to characters with more than 75 games submitted, and that have submitted games in 2007. But that's based on just the two characters, which isn't exactly a lot of data to work from.

I wish the Character Watchlist did actually list when characters have new games submitted. That would make tracking changes in rank a lot easier.
