Emcee
The event organizer can add one or more Emcees on the settings page. Emcee names show up on the front page of the event. Clicking on a Emcee name will take you to a page with actions and reports that are of interest to Emcee.
On this page is a button that will take you to a list of heats. Clicking on a heat will take you to a page with more information about that heat including the number of couples. The left and right arrow buttons can be used to advance to the previous and next heats. Clicking on the Heat at the top will take you back to the heat list which is useful if heats ever are done out of order.
For events where the Event Organizer has uploaded songs for dances, you will see controls for playing the song associated with the current heat immediately above the list of participants on the floor.
Pressing the space bar on a page with an individual heat will update monitors containing the heat number and will cause lists shown on mobile devices to advance.
