I received an auto-renewal reminder email from GoDaddy this morning. When I looked at the domain name that will be auto-renewed next week, I realized it was for a domain name I previously sold via Dan.com. The first thing I noticed was the account number in the top of the email was different than my account number, so the domain name is definitely not in my account.
When a domain name owner sells a domain name via Dan.com, he is given two options to get the domain name to Dan. The seller can either start an account change to the Dan holding account at GoDaddy or unlock the domain name and provide the transfer authorization code for Dan to transfer it to Metaregistrar.
