The most recent significant improvement is the full screen expand option found a the upper right of the chat area.
We have always offered a many-to-many chat room configuration.
In addition to this chat room configuration you now have the ability to use channel chat rooms and one-to-one chat rooms.
A channel chat room allows the room host to view all chat room participants webcams and the room participants may view only a large broadcast stream of the room host.
The one-to-one chat room option allows two persons to view each other using large broadcast stream format.
