Chat

The chat box sits at the bottom of your screen.

What it's for

Chat carries your table's written exchanges, and also displays dice roll results, with the name of the player who rolled.

See Dice.

Writing

Click the input area at the bottom of the screen and type your message.

If the cursor doesn't respond, check that you're in HUD display: right click toggles between camera control and the interface. See Switching between building and playing.
