I've seen a couple of complaints online from people who saw the video of the Hotmail "Kahuna" release but couldn't get into the beta. The beta is now open to the general public. If you'd like to sign up for the beta, just click on the link below and follow the steps listed

I'm totally digging the beta and have definitely been impressed with the improvements in the service. Kahuna is gearing up to be an excellent release.
