This is a really simple plugin I hope you get some use out of it.
/a <message> - Sends a message to staffchat. Aliases are /sc, /adminchat, /staffchat.
/tsc - Toggles staff chat on and off in chat. When you send a message with this on, it will automatically go to staff chat. An alias is /sct.
staffchat.talk - Gives access to talk and receive StaffChat messages.
Ya this is all there is to say really.
