So... how do you get multiple miners to send funds to the same witness (and therefore "wallet")? Its been written elsewhere you cannot use a witness on multiple accounts or something ?
"Now, for any given account, you do NOT want more than 1 node configured as witness. Otherwise, multiple nodes will try to generate a block at the same time and the network may even consider it malicious activity and punish you."
From: https://steemit.com/mining/@orly/mining-steem-on-multiple-machines

But it also says:
On only 1 (preferably the most stable) node:
In addition to the miner entries, have witness lines for all accounts

Which is to say only one PC has a Witness configured, the rest dont, which flies in the face of "rewards goto the witness" not the Mining accounts as PC2 doesnt have a witness specified!?

So confused!
