I recieved the notification from Azure Platform Team that the CTP accouct will be closed at the end of the January 2010.
If you decide to not continue with upgrade, on February 1, 2010, accounts will be disabled and SQL Azure databases will be made read-only. Finally they will be deleted on March 1, 2010.
Trying for 2-3 months the Azure platform just for test and I spend good time with data in cloud, also using some tools about Azure. I have decide to not continue for the moment.
Have nice SQLing with Azure if anyone decided to continue next...
