So, you say you do not have a mic. Who Cares, at least you can come in and hear your teammates
Also, when you joint be sure to Join the correct channel. By default you first Connect to the Use Only After 7pm CST M-F Channel (which you can not talk in).
Now look at the picture below. Note how there are players on each team and how their green lights are lined up. If you join and your light is not in line with someone else, then you are not talking to anyone.
EDIT: I changed the names and position of some channels.

In TS you can create keybinds real easy to switch channels without leaving the game. I suggest you RTM and setup keybinds.
Lastly, this is for the Inf Players that join up on GD Server. I wished I could allow any Inf player for any Inf Server but I can not (Bandwith issues). Also, as the top channel says, use only after 7pm CST M-F [all Day S&S]. Which are the time that GD Inf Server is unlock.
