Mumble/Murmur is a fabulous and high potential application with broad implications. However, for it to be useable in any mainstream application (e.g. at schools, business, etc) there must be a way to disable the public listings which contain offensive and inappropriate content. I'm hoping the developers will see this as an opportunity to widen the appeal of this otherwise quality app.
Mumble is extremely secure.
Love the voice wizard setup. Sound quality is excellent.
