Are you still using an old NCsoft master account? If you are, then you’re going to want to migrate to the new system before May 1st lest your account be deleted forever.
To encourage long-time players to bring their accounts up to snuff, NCsoft is offering 400 NCoin to those who migrate to the new system. If this applies to you, all you’ll need to do is log into your account and follow the instructions. The company said that it will begin deleting old accounts in early May.
