Hi there guys, super excited to be here - just joined the pool (got my miner on Thursday)

Just wanted to find out, I know the pool works off a PPLNS Payment system.

Could someone please take the time to break this down and actually explain how it works and what total payments I could expect for a month? (Currently mining with one S9)
Just curious on how it works, what the profitability is like etcetera

Sorry for being a noob.

Thanks
