No, if you give out your serial number you run the risk of having it spread beyond your control. Your serial number has your email address encoded within it. This means that if someone using your license sends us an error report, we end up sending responses to your email address. As well, other users may pose as you and take control of your license by changing the email address associated with it. If a serial number becomes flagged as having been used on too many computers, we reserve the right to cancel that license and it will no longer work in future updates.
