No more new messages? Close the guestbook. The button disappears from your invitation, and the messages already there are kept. You might do this a few weeks after the event, once the last messages have come in.
How to close it
In your dashboard, click Guestbook next to your invitation.
Click the menu (the three dots) next to the Guestbook heading.
Choose Close guestbook.
Close guestbook is at the top of the menu.
What changes
Guests no longer see the Guestbook button on your invitation.
Below the heading of your guestbook page it says The guestbook is currently closed.
In your dashboard, choose Change details from your invitation’s menu. Tick Enable guestbook and click Save settings. The guestbook is open again, set to Public.
Don’t leave that box unticked. If you save Change details while Enable guestbook is unticked, the guestbook is switched off completely and disappears from your dashboard. So download the guestbook before you close it.
