Windows Azure: Cloud Computing in Application Services

Great information and thanks John & Dennis.
I am very much excited on this technology. I had registered in
www.azure.com and I have installed azure SDK to work on some sample (ASP.NET Hello world sample) but whenever I try to create host service none of the services are availble there. I noticed the below message.
Register for Services*
*Due to pre-release CTP status, you may be temporarilyplaced on a waiting list for certain services.
Also I noticed that, under the "Account" section in the site, I need to put Resource Token ID and need to claim the token. But I haven't recieved any email with that information.
Any body know how I can get host services to work on some samples ?
Yeah
