A way to block users from viewing channels

  • Hello,

    I am a fairly new user to mumble me and my group of guys made the change from
    vent just recently. We play a very competitive mmo that has a lot to deal with
    strategy, spies, numbers, etc. We are looking for a way to make it so
    unauthorized users that connect to mumble can not View our channels. At the
    very least view who and how many people are in our channels. I have looked for
    several hours on this topic and can not find any helpful information on it. If
    you can help out that would be great.
