Saw this extension mentioned several times, so I decided to check it out. There are still just over 500 of 999 remaining. Unfortunately this extension has the same issue as .CH where it cannot be pushed through GoDaddy. But regardless, if the prices goes up, transfer fee's become irrelevant if domains are selling in the XXX+ range. As a disclosure, I only own one NNN.CZ. Someone posted that CZ might mean Chinese Zodiac.
