You are nearly finished with the mod installing. There is only two things left to do. Lets first take care of the correct Task Force Radio installation!

1. Go to your Mod folder (where the downloaded mods are saved)
2. Go to "STAF Main"
3. Go to "@STAF_Task_Force_Arrowhead_Radio"
4. Go to "teamspeak"
5. Double click the "task_force_radio.ts3_plugin" and install it

Thats all...Now you should be good to go. The best way to know is, if you just try to join our server.
