Any SWBF2 admin or Clans with SWBF2 servers, can set up their own leaderboards for their server at:
The site will keep track of kills, deaths, KDR, scores, and sort them for you according to faction, map, game mode, players stats, etc. Clans can set up their own private leaderboard for their own community. The site has also got a keyhash search tool for SWBF2 admins who want to check and see what alias' (or other names) a player has been playing under.
You can probably forget about the official Lucas Arts leaderboards. Even when they accurate (first month of game release), there were problems with player stat padding. One of the main issues was that you could set up a server... PW it... load it up with bots on easy... and play all night by yourself and simply rank on up. You're also ranking against the entire community of players that used to play constantly and consistently for years. At SWBF2Stats.net, the leaderboards are as up to date as the server admins want them.
