The last tab in the Activity Management section is Meals. If you will be offering meals during your event, this is the place that will allow you to keep track of those numbers.
You will begin by clicking on the Add Meal button, and then filling in the basic information - Meal identification name, and the time block that it belongs in. If you have already completed your schedule, you will simply select a pre-determined time block. If you haven't yet, you can create a new time block here.
