Dear Robbo,

Congratulations on recently completing your 500th SETI@home workunit.

Through your support, SETI@home has grown to become the largest distributed computation on Earth.

We at SETI@home greatly appreciate the 1.63 years of computer time you have donated to the project,

and hope that you will continue your support. As a small token of our appreciation,

you may now download and print an official certificate stating your achievement of this goal,

Thank you again for your contribution.

Sincerely,

The SETI@home Team
