For example, you want students to sign up for a meeting time. You only want two people to sign up for each meeting time. Using Google Forms and Choice Eliminator, as soon as the second student signs up for a meeting time that time will no longer appear on the list of available slot. NOTE: This add-on will only work with multiple choice, checkboxes, and choose from a list question types.
