If you get one share you know its working.  You won't necessarily get a lot of shares so at first it is a bit of a leap of faith, but thats the same with a lot of multipools.

You won't get regular payouts as they exchange what they mine for Vericoin.   So usually what you mine today, you will get payed for tomorrow.  Once you stop mining you will also get payouts for a day or so, depending on what coin they mined and how easy it is to exchange.
