OMG !! I went though the thread and though "bummer, to offensive for me". Then I realised it was integrated with Bitcoin-QT. So I went in preferences on my Mac's QT and found the Coin Control featured and activated it. How cool! Just to get it straight, as this starts to get too technical for me. We're payed to the 1k address. As I understand it, vin is tied to a raw tx hash, not an address. When you send funds out, the change is sent to new "hidden" address. So lets say for example, without coin control, I have 1005 DRKs, and send 1DRK, I would break up the remaining 1004DRK to a new receiving change vin - this breaks the MN. If you select the 1k deposit in Coin Control, it will send the change back to the same address, but that means a brand new tx hash anyways? In this case, I would receive back 1004k, and not the 1k deposit necessary keep the MN active. I assume my reasoning is wrong... but do we have to "zero" out the 1000k deposit, or can I just move out 1 DRK, leaving 1004DRK in cold wallet and node active?
