Wedding wire has a lot of convenient things to keep your wedding organized and updated but can your guests sign in to your account and RSVP themselves instead of sending reply cards. Bwedd.com seems to have a lot of the same features as wedding wire but to use all of them you would have to pay over $150....The point is trying to save money but I also don't want to confuse the heck out of my guests...I also found anRSVP.com...anyone used it?
