I apologize that I haven't been able to contact full node owners yet. We ran into complications with our first node's stake being stuck in limbo with an RC2 hot wallet setup, our first node. This problem isn't an issue with RC3 cold wallet setups, but its consumed a lot of my node operations/setup time in the last few days trying to figure out what went wrong.
Fortunately, if you only have a node or two, this cold wallet process I worked out should work well for you. My procedure would makes sure you backup copies of your wallet.dat *and* the associated darkcoin.conf file for it, so you can pull up a node as needed and control some key operations if you had to restore the files you back up both locally and on USB media (and/or alt.).
GOOD NEWS FOR FULL NODE OWNERS! The largest bloc of Batch 1 Full Node reservations have been moved back to late July so that it can be worked on in-person, together.
That means if you're in Batch 1 Full Node reservations I should be able to get to your full node in a timeframe of "days" instead of "weeks." I need to work on the Partial Node spreadsheets first, but I should be able to start getting to the first Batch 1 Full Node reservations tomorrow.

For your patience, you basically let the Partial Node owners be the guinea pigs who worked out all the bugs before you risked your DRK in a newfangled cold wallet storage procedure. As for things that slowed me down: the multiple wallets for multiple node issue was a big stumbling block that wasn't proceduralized very well there, that required offering bounties tothe community to try to get answers.
If you're wondering: the cold wallet storage method works great! Unlike RC2, in RC3, it doesn't risk your 1000DRK sent to some external address and you control the encryption password and hold access to the wallet.dat file itself. "Payments" to the zeroth address to register as a masternode operated by a cold wallet stay internal; they show up as a self-payment and the local DRK total you started with remains the same.
