“Dear Matt,

We truly appreciate your interest in Google Compute.

At this time, the Google Compute feature is only available to a small
number of randomly selected Google Toolbar users. We intend to roll out
this feature to all Google Toolbar users in the near future. If you’d like
to be notified when the feature becomes available, please consider
subscribing to our Google Friends Newsletter at
http://www.google.com/contact/newsletter.html
.

Besides, please note that Google Compute is not supported on Win NT
currently (although it will be supported soon).

Thank you,
The Google Team.”
