So I need some advice about how to have guests RSVP for our wedding. Being 2012 we figure most people have internet access. Is it ok to direct guests to our wedding website to RSVP instead of the traditional way of sending the RSVP card with envelop and stamp with the invites? It's not a matter of saving money with the stamp costs, we're just trying to keep our wedding as green as we can. We just don't want to offend anyone in the process. Any advice??
