Junk. There's something broken in the sms system in this app. I never received the 4 digit code to register my profile. I had to uninstall and reinstall it to register. Next, I setup a test event and the invitation text sent 1 of 2 tests right away, never got the second text that presumably contained the critical link to join the party. The text message: "XXXX & XXXX signed up for The Guest to get your photos from the wedding. Can you download the app and sign up here: (1/2)"
