Just a heads up going to be shutting down the mumbler server by end of this month
Canadian dollar sucks so I'm penny pinching on things not being used much (by myself and/or others):D
Alternative voice chat + communication tool (that some of you probably already use) : Discordhttps://discordapp.com/
It's "free" all in one comm tool (cost is whatever information it gathers on you)
Has chat function, hashtag function, persistent rooms/history + voice chat
Discord themselves host everything.
Also lets you invite people to temporarily join voice chat channel via web browser link
