> Note that this means you are technically not the owner of the domain, and you may be limited in your ability to transfer it, sell it, or do other things with it. This is a myth. ICANN has published requirements on how private registrations must operate; ownership of the domain always goes to the paying owner, not the registrar.
That's interesting. Do you know where the requirements are published? I've read language recently from at least one registrar specifically stating that private registration prevents transfers to other registrars. Maybe this was before these new requirements were published.
In my recent experience, private registration prevents transfers because you are unable to receive the email message that contains the code you need to complete the transfer. I am still able to transfer my domains, but I need to turn off private registration first, so the email is sent to my real email address. This seems like a silly problem, and one that the registrars cold solve if they wanted to, but obviously they don't.
