If you were an attendee at the PDC and you signed up for a Windows Azure token with the same Live ID you used to register for PDC, you should have received a token by now.
If you don’t have a token, let me know what Live ID you used, and we can check out what might have gone wrong. My email address is on the right side of every page on my blog.
For everyone else, we’re continuing to add capacity all the time, so please hang in there! In the mean time, download the SDK and develop offline.
