I recently developed a custom wordpress wedding theme. Designed to be minimalistic yet robust with photos, information, and functionality. The site has a fully functional RSVP plugin which we will be using instead of the traditional snail mail. I'm excited to learn how it works for our guest. The site is also responsive making it easy to use on all device widths.
Also Integrated is an instagram hashtag feed that encourages guest to use our hashtag to share our special day. You'll even find a count down of days till the ceremony kicks off.

I used Magic Mockups to quickly add screen shots to staged device images.
