So I can create a MPH account but define our individual rigs with different names and then point these individual named rigs to separate wallets?
after creating an account you need to create workers on the mph site... those name you'll be using when configuring your individual rigs in AM
just to clarify, you should have no problems mining the rigs to different accounts in MPH (one for you, one for your brother)
in AM you set up the miners and override the online service pools by Right Click miner -> Properties -> Override pool settings
check the boxes for the pools you want to override (you can also do that for custom pools, just use that for 2 sets of custom pool groups) and for example MPH, you'd put in the Worker name field in the format: MyOwnMiner.Worker1 for your rig, and MyBrotherMiner.Worker1 for your brother's rig...that will point one miner to the account MyOwnMiner, and one miner to account MyBrotherMiner...and so on where you set different worker names (Worker2, Worker3....etc) for other rigs/miners.
This works the same for other online services except you put actual address in the respective fields.
