Sometimes a player is not aware it is his/her turn to bid or play. Currently, everybody is trying to "wake him us" using the chat, but the chat is pretty subtle and many people don't really see it. My suggestion is to add a button or a checkbox: "FLASH" next to the CHAT button, that instead of just showing the text in the chat area, it will flash it in a small window in the center of the "table" to draw attention
