How do you slim down a guest list? I want to share my wedding with the whole world, especially my family and friends. Should I walk up to my loved ones and ask which of them are perfectly happy with looking at photos after the fact? It must be done and it will. I just want the world (and my family and friends) to know that if they don't receive an invitation it is not an expression of my feelings for them.
