so far it looks like it is the way to go- the 1 hps is it building- I'm letting it sit overnight and see by morning if it starts mining for real ... additional miner accounts- here's what I read "I was informed that you only should have one active witness on your node computer. On all of the slaves leave the "# name of witness controlled by this node (e.g. initwitness )" blank with a # but you can copy over the configuration in line below it "# name of miner and its private key (e.g. ["account","WIF PRIVATE KEY"] )""
