Fantastic for waitlist and very good promotion function. There is no doubt that this is a golden star for waitlists. And very impressing sosial marketting refferral system what simplicity regards. I would like to use that in stead of two competitors (bought on appsumo) for simplicity - but I dont need waitlists. I tried for instance to register for a restaurant promotion, where two people from one company could have a free lunch. Unfortunately you could only register one person. Should develop more user cases than waitlists, because the promotion system for social media is on the top of simplicity. Pleas do and come back to AS
