LOS ANGELES (AP) -- A Web site that has details about the nuptials of "Grey's Anatomy" duo Meredith Grey and Derek Shepherd — and an invitation to RSVP for the event — drew 1,400 replies in the first 24 hours.

Not bad for a fictional couple.

The on-again, off-again duo known as "Mer-Der" are set for a May wedding, and series creator Shonda Rhimes enlisted the TV show's staff and ABC's marketing department to make the most of the occasion.

The online site, which is built within theknot.com, celebrates the pair played by Ellen Pompeo and Patrick Dempsey. It includes a gift registry page, where visitors are invited to donate to charities that have a connection to the show's story lines.

The Web site says the wedding is set for May 14.


ABC is owned by The Walt Disney Co.
