SO's sister received a wedding invitation today from a girl she went to school with. And while she would love to attend, the wedding falls in the middle of her trip to Africa this summer so she can't. The invitation didn't include an rsvp card so she had to log-in to their website to rsvp but when she logged in there is no option to RSVP no! I suggested put her name and zero as the number attending but that isn't an option either. So now we're not sure what she should do. She doesn't want to be rude by not responding but this couple hasn't made it easy! So I figured you wonderful ladies would have some suggestions!
