My best friend, Andy, helped us locate and install a guestbook feature that lets people upload photos and write a brief bio about themselves. In my mind, it's a great way to build community and help people from two different camps (Sara v. Matt) find common ground before it comes time to mingle.
We asked a few of our closest friends to sign it now as a way to model for other people what the purpose is. This picture is from Matt's friend Noah. His corresponding bio: "Wassup single ladies!!!"
It cracked us up (immensely!) but, in the end, we decided to censor it. We figured there's enough in our non-traditional wedding to freak out the grandparents; we didn't need to add more fuel to the bonfire. (But Noah, we love you!)
