I have just set up a Mumble server. The people on the Streaming reward tier can have full access to this (under the assumption it is not misused). It is passworded and the password will change sporadically. I will join it for some DvZ and PMC games, or other games, or even just to hang out occasionally. I don't promise to be there every day but hopefully we can do some interactive DvZ stuff or whatever together. More details coming.
