This is the web address your guests visit to see your invitation, reply and find all the details. You choose the first part; we add the rest.
For example, if you type mias6th, your guests go to mias6th.everygathering.com. It's printed on your invites, in your emails and on your QR code, so pick something short and easy to type: your names or the event, like sarahandtom or davesretirement.
It can't be changed later, and nobody else can use it once it's yours.
Letters, numbers and hyphens only. Lowercase. 2-40 characters.
