You can join the official Bulgarian haxball community TS3 server using the following ip address 51.68.62.28 or clicking this very ugly blue link:

In order to prove their identity, all haxball players must be able to join the TeamSpeak server anytime before, during or after matches/competitions they played in, if an administrator or the enemy team asks them to.

If you don't have TS, you can download it from HERE.
