I've been avoiding github for a long time now. I've got a bunch of hacks I've accumulated over the years and now figure that github is as good a place as any to put them.
So, my first push is an experimental Mumble (voip) server I wrote a while back in Erlang. It compiles and runs a basic voip chat server but is probably not up to date with the Mumble spec. Plus there are some half-baked voice mail stuff included that doesn't work yet. It's called Maunder.
I don't expect anyone to fork it (or contribute), but it is better for it to live there than to exist solely on my harddrive.
You'll need a mumble client to talk to it.
