Any Insurgency: Sandstorm community server can host a stats-enabled game. Enabling stats on your server also enables experience gain while playing on the server. The only requirement is that you must use a Steam GSLT, and you must not have a server password.
Visit the GameStats Token Generator and authenticate through your Stream profile.
Click on "Generate Token" which will create you a GameStats token.
Your token will look something like this:
-GameStatsToken=1417264D1C6549CC95E10CA1E9BE8F09
Simply add the generated token to your Startup tab GSLT TOKEN section and stats will be enabled! Make sure not to share your GameStats token with a third party. Server admins found to be abusing the system will have their tokens revoked, and your account will be investigated. If you suspect your GameStats token has been shared, please generate a new token.
