In my family, we have quite a few people with the same names. When I did a test-run of the RSVP feature on my wedding website, I typed in one name that should have had two entries and I could only find one listed with his spouse. The single person with the same name did not show up. I tried it on a few other names with similar circumstances and the same thing happened. What is going on and how can this be resolved? Most people won't have a problem RSVP-ing, but a select few will definitely have troubles.
