Okay for my wedding we didn't use the R.S.V.P that the Knot has, each invitation had _ of # that we chose attending. We had people cross out the # we put and add people, when confronted about it the people they added did not meet the criteria we had set as far as plus ones go, and they still brought them even though we had made it clear that the invitation was only meant to include certain people. I have been to two weddings now that have used the R.S.V. P on the knot and I love it. If I had a do-over we would definitely be using the R.S.V. P on the Knot. The thing I like the most about it is that guests can't add, you find your name and r.s.v.p for whoever is in your invited party. Now the thing is I'm hosting a baby shower for someone close to me and am looking for some type of site where I can put in the guest names and they have to find their name to rsvp and can't add people. Does anyone know of a site that replicates the knots guest list this way?
