Fix the chat system so that changing experts doesn't break chat, or add functionality to switch back into chat mode from Q&A mode.
In many categories, using the live chat system is essential to providing a rapid resolution to the customer's problem. When the conversation drops to Q&A either through a bug, an expert opting out, an overzealous IR by another expert, etc... it totally disrupts the customer experience and can turn a resolution that may take less than an hour into a multi-day ordeal for both the customer and the expert. Furthermore, when an expert opts out of a question that is already in chat, other experts may be less inclined to pick the question up knowing they are now stuck in Q&A mode. Please add functionality to make it possible to go back into live chat mode from Q&A mode.
