The Invitation page is often used for basic and logistic information -- event name, date, time, location, and directions. You can rename it from Invitation to say whatever you want, in case you're not having an event.
- Edit the invitation by clicking the "Edit" button in the top right corner.
- Then fill in whatever information you'd like to see.
Don't worry -- if you don't want to include any of the fields, just leave them blank and they will not appear.
