Hi everyone! Just a heads up, the Viper Gaming mumble is free to use for anyone in need of one. I usually just password protect a channel for teams. I don't know if there is a need for this kind of thing anymore, but I figured I would throw it out there anyways.
Mumble info can be found here: http://www.vipergaming.org/mumble/
If you register yourself you can make a temporary channel in the Temp area, or if you'd like a permanent channel ask here or find me in the mumble.
Hope the TF2 community is well, I wish I was still playing from time to time.
