I realized yesterday, looking over our expenses for our scaled down wedding, that we don't have a guestbook. First thought, was to go amazon.com and see what's available and then I talked to my fiance and he suggested a virtual guestbook where guests, regardless if they're attending in-person or will watch via youtube, can leave nice comments for us. I made it using google sheets since that seemed to be the easiest option.
But I was wondering if anyone had done this and what service they used?
