Solution...for those of you who cannot contact friends when in Casual etc. When you first log on (or at any time) go to bottom right of the 'People' tab and check the SHOW OFFLINE button to ON, make it orange. Now you will see all your contacts, in alphabetically order, those off line will be marked with red buttons, those online with green, those online and playing with yellow. You can send a message to any of your contacts now, regardless of where they or you are.
