I'm a very private person. I use social media only to keep in touch with very long distance friends and family. I don't share every one of my pictures online. My wedding is special to me and I'd like to keep it private from the "world", at least until I get my wedding pictures from my photographer. Other people that didn't get invited to the wedding but were expecting an invitation would be upset/hurt if they see they pictures on facebook/twitter.
Is there a way to gently ask your guests to not post pictures of the wedding as it is going on?
