I have a guest that is invited to my wedding that is CONSTANTLY on Facebook & other forms of social media. My concern is that they will be busy posting details & pictures of my wedding as it happens. It's not uncommon for this person to post things every few minutes ALL day long, Quite honestly, I'm not sure how she keeps her job. I'm not sure how to keep this from happening. Is it rude to post something at our reception tables or someplace near the ceremony site asking that our guests refrain from posting information about our wedding? I don't mind pictures from the reception of people dancing & having a good time but honestly, I'd like to be the one to decide if pictures of my wedding cake, dress, etc make it to Facebook or anywhere else for that matter. Am I being too sensitive about this?
