Here’s how it works according to the Stageit folks:
Go to https://www.stageit.com/rik_emmett/rik_emmett_at_daryl_s_house_club/55914 , click signup to set up an account and then click the GET TICKET button. You will then have an opportunity to purchase credits (which Stageit calls “Notes” ; 10 Notes = $1.00). Notes allow you to pay for tickets to see shows and to tip performers during the show. This show is “Pay What You Can,” which means you can pay whatever you can afford (minimum 1 Note). Once you have Notes, they can be used for any show.
