I don't understand why we need a NXT account but whatever, I'll give it a try.
We need a valid NXT address to issue your Kora tokens on the NXT asset exchange. Once we have the Kora network up and running you can exchange Kora tokens on the NXt AE for Kora coins in a NXT wallet.
So is it cool if I register using my NXT address from my online wallet at myNXT.info?
