It has happened once too often... someone calls and tells me the person who designed their website and who has always done their web maintenance has disappeared. Their domain is now up for renewal, they don't know how to do it, and they also want to switch hosting. So I take a look at the information for the domain, and find that the registrant for the domain is their web person, not them. So now they can't get into the domain registration without herculean effort. What can be done?
