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.
I am not able to see the video of these tutorials. If I could it is really a good job
