I read somewhere about a wedding website that has RSVPs that limit the number of people a respondent is bringing. For example, you invite Mr & Mrs Smith only (no kids or guests) and when they find their name on the RSVP site, there's a drop down option for 1 or 2 people attending - no more. Three, four, etc is not an option because only two people were invited. Does anyone know the sites that have this feature? For the life of me I can't remember the name! Thanks y'all!
