To help us facilitate interaction with the DayZ general public, I have setup Mumble to allow any community member to interact with folks in Unregistered.
Once we get 0.59 pushed out and have our own server again, we will need to be able to interact with the public for our HEROs for Hire type missions.
This will also allow our community members to play with their friends temporarily in unregistered until the friend is vetted by a HERO*.
