Since masternodes and darksend work for DarkCoin I see no reason why it wouldn't work for SpreadCoin. If you have any suggestions about how masternodes/darksend can be made better you can say it.
I will leave the names Masternode and DarkSend as is, I don't see any reason to rename them.
Also I want to write a white paper about my changes and original DarkCoin features themselves, current DarkCoin white papers are either outdated or describe only part of the necessary information. I want my cryptocurrency to have a good description about what it is and how it works.
Totally agree, no need to rush. Better take the time and do it right!
