I made this topic before, but it was lost. :[
Anyways, Alot of people roleplay on WOS. Common groups are LSPD, LVFD, SFFD, and SAPD. Well, Why not have a radio command, like /r (message)? You could turn it on/off by typing /radio on/off. So far we have been using gangs, or teamspeak, and to problem is No one will leave a gang to join a radio gang, not to mention stuntwars are lame with a radio gang, and teamspeak is hard cause no one has a microphone half the time.
Feel free to leave your feedback, or If you have more to add post it.
