The Great Chat-System debate

As you may know, Chatzy.com are no longer maintaining their website or chat system. There are now multiple issues affecting our chatroom which are not being addressed, so we have chosen so far NOT to renew our premium membership with them.
This decision means chat history and personal messaging are no longer available, and the room is limited to 10 people at once.
There is now debate over what chat-system we should use moving forward into the future. Do we stay with Chatzy until they shut down unexpectedly one day? Or do we move to another chat service? Have your say in the poll below.
