If you are muted, than you can only talk with quick chat.
The only method of talking is to use QuickChat. You can use access the QuickChat menu by either clicking the bubble next to your name in the chat window, or by hitting enter.
Another possibility is that you are in a "quickchat" world; one in which only "quick chat" is enabled.
That means you have been muted. You cant talk because someone reported you for cussing and u got muted for a few days.
you dont have to click on anything just type and press enter its easy:)
just type what you wanna say and click enter if u want to use quickchat, press enter and choose what you would like to say
