Bubble Chat

Bubble Chat, as opposed to Classic Chat, is the type of chat you see above players' heads. It can only be seen in places with Bubble Chat enabled.

In order to enable bubble chat, go to one of your places and select the "Configure Place" button. Scroll down to "Chat Settings" and select "Bubble Chat" or "Both" - selecting just "Bubble Chat" will mean there will be no chat log, just bubbles above the players' heads. "Both" will make it so there will be a chat log, AND bubble chat.
