Only few people are using it right now, with GB's being the most numerous users as I have been able to see in a last couple of days.
Anyway we got our permanent channel, it just isn't passworded. Alhough Thal made me administrator, those rights somehow vanished (the software is still in beta anyway), so we must do with the unsecure channel for the time being.
That isn't such a big problem, as there are barely players in the main lobby of teamspeak, let alone German Borg channel.
Also, don't expect it to work right out of the box, cause your microphone and teamspeak settings will probably need some adjusting to work properly.
