mining pool is where you put your EMC info in. Workers is where you setup a worker with your EMC pool info as your private pool. Once setup you will have a Username generated and a password for gpumax along with server info. Point your miner at that and bam you are using gpumax. PPS price is up to you.
You have to setup a pool first. And you use the url your miner is normally pointing at for the pool url. And you use the username and password of one or your normal miners for the pool username and password.
then you create miners in gpumax that connect to your pool, and as stated in the post above, there is a username and password generated that you will need to redirect your miners at home to.
took me an hour or so plus a lot of reading to figure it out. Definitely lacking in documentation...
Much appreciated, Gentlemen!
