How do I create a What to bring list?

For an event taking RSVPs here, enable What to bring under Manage → Features. Open its tab and add the items you need, with the available quantities offered by the editor.

Guests who reply Yes or Maybe can claim an available place from their guest page. Review the claims as the event approaches.

If you change the list after people have chosen, tell anyone whose contribution is affected. Turning the feature off hides it; it does not erase the existing list.
