Well, you know how you can use voice in DOD. Well, not all games have voice - and some people want to use voice to talk to friends in other games or applcations so vent is just the voice part. You connect and talk to the other people who are connected.
And dont appologize. Why do i always get appologies from people who just want to learn and dont need to, and never from the people who are rude, mean, or do things that can potentially cause harm and or lie. Stupid backward world.
