Sam, you have my apologies. After rechecking HiveMail, and finding a post by tubedogg, I found:
"You are, however, allowed to sell your license. This means that you delete all copies of it that are in your possession and transfer the license record to someone else. (After selling the license, to complete the transfer, visit the Member's Area and click Transfer across from the license number, then follow the on-screen instructions.)"
