My fiance and I are having a very small, immediate family only wedding next June followed by a dessert reception for all our family and friends. I've seen invitations that request RSVPs be made my email or text...is that too tacky? I keep going back and forth on this...since we want our celebration to be less formal than traditional weddings maybe it would be ok? How would I handle grandparents and other family and friends who don't have a computer or know how to text? Help!
