And then somebody starts a DRS which you will know nothing about, because all the contact information has been changed.
Eventually somebody at Nominet phones you, because they recognise your name. They promise to sort it out.
However the DRS is lost and you get a 'black mark'.
You complain to Nominet that they issued a DRS to the wrong person and accepted his response. You then discover that Nominet has no procedure for sorting it out when they don't follow their own procedures.
Never release the IPSTAG while a domain is still in your name.
