Is there any way on theknot.com wedding website, to give the person who is about to RSVP the option to put the name of a guest. We realize that there will be invited guests (who were not specifically invited) who will bring their significant others to the wedding and reception, so we want to be sure that we have name tags for them when they are seated at the reception. Can somebody please help. We have not figured out how to set this option or if the option is even provided by theknot.com. Thank you for your help
