I had a game on the Dev Server #2 the other day (well, I didn't play, but I was asking questions) and we got onto the topic of the VOIP facility. I asked if there was a way for a mute vote on the VOIP. Tuple asked on IRC and told me it would also be good if I put it on the forums. The response on IRD iirc was negative at the moment. I thought I'd ask the same question on the forums for everyone's sake.
Will there be the ability to mute players from VOIP when 1.2 comes out?
