     sent us an e-mail that has a document about the location where the author live. Even though the information true and led us to the arrest of the author, the sender didn't mention about himself so that we are unable to give him the $500,000 reward. And the author of MyDoom has be found to be a former Microsoft's employee fired becuase of his discipline. Now Microsoft and SCO are confused to whom to give the reward.
     Microsoft has also released a new form that the sender can fill in and take the money. The sender is urged to send his/her post address to Microsoft or SCO using the attached form.
