[SOLVED] Xonstat ID

How can I set up a Xonstat ID or receive one?

You need to play on a server that is using stats (they got a little bar-diagram-icon on the left side) and they you will appear here: http://stats.xonotic.org/players

And your IP address can only receive an ID once a week. If you've launched Xonotic on a different computer or user account in the past week and have a static IP, you will have to wait.
