Rank is a number used to determine on how widely known you are in PvP. The
only way to get Rank is to gain Fame, which can be gained from winning battles
in the Tomb of the Primeval Kings. For every certain number of Fame you earn,
you get a Rank. Once you hit Rank 3, you will get a special Emote which makes
you stand out among everyone else. To activate this special Emote, type
/rank or /fame in the dialog box in Guild Wars. You receive a new and better
Emote when you increase every 3 Ranks.

RANK    FAME    EMOTE GAINED  
1       25      -
2       75      -
3       180     Deer 
4       360     Deer
5       600     Deer
6       1,000   Wolf 
7       1,680   Wolf    
8       2,800   Wolf    
9       4,700   Tiger

There are more Ranks available to players by getting more Fame, but the
values to get Rank 10+ are unknown.
