WeddingWire allows users to use the RSVP application by adding the guests to the guest list first, then adding the guests to the specific event. This, in turn, allows the guests to RSVP themselves, rather than use reply cards. A WeddingWire account is required for guests to RSVP.
Apart from the RSVP application, WeddingWire offers the choice of how guests can search for themselves on the wedding website, either by use of their first or last name. Furthermore, the guests can also choose their preferred meal for the wedding, since an option of configuring meal choices is provided on the WeddingWire account.
