One of my domains is registered with NameTerrific as well and I haven't been able to transfer my domain out to a proper registrar as NameTerrific does not respond to my auth code request. I had previously registered my domain with NameTerrific as he accepts bitcoins.

Do not consider registering your domain with NameTerrific. You have been warned.
