Thanks, Lyaffe. Added the MacOS install info to the OP.

Cryptsy is dragging their feet on this.  Sent them a few emails but they're behind and short on manpower so I think those with NAUT in Cryptsy will be delayed at least a week.  Maybe more.

what about for those that dont want NXT based naut?

Hate to sound unsympathetic, but:
Brian Kelly is the developer/creator/backer of the Nautiluscoin project, and he wants to move NAUT over to the Nxt MS system.
In the absence of any community-based development or initiatives for NAUT, this makes BK the overall project leader.
Holders of the 'old' PoW based NAUT are completely free to refuse the swap, but only the new NXTNAUT will be used in the Drachmae project and further developments, so any holdouts will find themselves with 'old' Nautiluscoin that no longer has any form of support from BK or the Drachmae project.

I'm not trying to scare you, it's just how I see it.  I have my stuff on cryptsy too but I'm not tech savvy so I'm gonna wait until Cryptsy does the swap.

Sent you through one too.  Thanks Dave

Made the nightly payouts, have fun with your NXTNAUT, people !

Current total is (as near as dammit) 2.9 million NAUT redeemed,  from a theoretical supply of 5.3 million. This translates to 55% converted from the total NAUT supply.

Just made the NXTNAUT transfers for tonight, as usual you can see them here:

On account security: just make sure you use a good passphrase, the default passphrase generator used in the Nxt NRS client is secure.
As Nxt uses a brain wallet, password security is the only thing you have to worry about. There are no local wallet files that can be lost or stolen.
Watch out for keyloggers and Trojans, think about using a secure password manager like Keepass: http://keepass.info/

Lastly: some of you may have noticed that a mysterious (and very small) amount of NXT has appeared on your account.
If this happened to you, use some of it to make an outgoing transaction (like setting an account name).
Your first outgoing transaction publishes your account on the Nxt blockchain and increases its security.
This is a public service announcement from: http://nxtfoundation.org/

I have been trying for nearly a week to work with Cryptsy but they're really busy and they're behind other important projects so I couldn't get a solid timeframe.  They may do the swap in a few days or it could take longer.  Really hard to say.

I would suggest doing it manually by withdrawing from Cryptsy if you're competent enough or just wait it out.  I have lost too many coins doing it myself so I'm gonna wait.

Good luck.
