Hello...new to mining and using SMOS. I have 2 rigs on SMOS. How do payouts work? Have had one rig online with dstmv057 for 36 hours and haven't received anything.

I guess these are my questions:
How frequent are payouts?
Is there anyway to change the payout threshold?
If I switch pools will I get a pay out for a pool that I only mined in for say 5 hours?
If I have 2 miners in 1 pool, will the payout be combined, or one payout per rig?
Thank you in advance...please help this noob!
