Dynamic Attendee Counter / FOMO Feature

Right now it is only possible to show the max amount of attendees. And this number won't go down when people sign up. For some events it might be good to have a functionality that enables us to set it so that the number shown on screen goes down with new sign-ups. This to stimulate people to buy their ticket and create FOMO. Make this a optional function tho, as for other events, where sign-ups go slow it is not a good thing to show that traction is slow...
