Since yesterday I've been unable to send any chats on the server, is this a bug or have I been muted? And if I have been muted what for? 

You have been able to talk, you said hi to me, sam and fox and a couple others who were on the server at the time earlier today

(Note: Date of comment)

 Ohh, it doesn't show up on the chat for me. Weird. 

 Was it on F1 or in the settings chat turned off

 Ah it was set in options to show commands only. Got it working now!
