When you first start up the Hub, it gives you a quick summary of the latest relevant news or warnings. You can follow these links to keep up to date without leaving the Hub.
Down the left are quick links for each of Apple's Professional video applications. These links take you to a start page for each application.
The first time you access any of the free areas of the Hub, you'll be asked for some anonymous demographics. These are only used in aggregate and no personal details are ever released because, well, there are no personal details. No email address or name is requested and no identifying information is ever transmitted.
