I have the Local chat basically done, I'm going to add to it a check to see if there are no people in the radius, and it tells you if anyone can hear you. I have two prefs for it, one is the radius (10 - 200) and another is if local chat is on or off. I like having the radius set to 120, I was camping on my private server with Goldenboy, FireFlamer, and Rathgarf. It was fun. The local chat added a challenge and a sense of reality as if you couldn't hear someone from far away, so if you got lost, there was only hope if you signaled someone somehow, or someone found you, or you found your way back home.
Next I will work on the Whisper local chat, and then the team local chat, and then the radio chat.
