Michael Grandel is the co-leader of the Baltimore Admins Group and works for the National Aquarium. They needed a way to manage building capacity for reopening after the COVID-19 closure, so they created a Salesforce app for members and various other constituents to make reservations for a specific entry time. As a LightningChampion, Michael has generously agreed to walk us through this 100% declarative app that leverages a wide swath of platform features: Flows, Community, guest users, custom metadata, custom permissions, Lightning app pages, and more. We have the opportunity to tag along with several other UGs on this, so hope some of you can make it.
