when nobody is in the room lobby you can create a room called 'lobby' and set a password.
When a user will join the chat - must join the lobby - he get 'The room password is incorrect'.
Little bug. Nobody should allowed to create a room called 'lobby'.
One problem more.
The minimum of caracters is 3 - it's okay.
But why is the maximum of caracters 11 ?
When i type in a nick with 12 (ore more) caracters like 'ketchupfreak' and i press the Login button nothing happens...
...why not more than 11 caracters ? Isn't good.
