Keeper of Statistics is an addon that collects data from nearby players in your raid or party, it can then display these statistics in the guildchat!
You must index players for this to work. duh:P
/KOS to index players in your raid or party
/KOS clear to reset all gathered statistics
!stats in the guildchat will bring up a random statistic for a random player
!stats playername in the guildchat will bring up a random statistic for a specific player
People that are going to be indexed have to be very close to you
The default statistics that it gathers are few, but it can easily be extended if you're a bit crafty and doesn't mind getting your fingers dirty!
(If you're this interested, just check at the bottom of the .lua file to increase the statistics)
(note: if you add more statistics, I highly recommend that you run "/KOS clear" and start to gather information again)
