One of my clients’ sister is getting married in a couple months and I just love her new app. Weddingbook. It marries Facebook and The Knot, giving brides and their family/friends access to special wedding details including their Wedding Party, Guest List, Wedding Countdown, To Do Lists and Guestbook. I wish I was getting married again (to the same man of course) so I can create a Weddingbook for myself.
