Choice Eliminator, a Google Forms add-on, will eliminate a choice on a form once a specific criteria has been met.  This can be used to allow students to sign up for groups or meeting time slots.  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.
