I just saw this short video of how a bride and groom are organizing their guest list of 200 with Google Docs. It's definitely 2010, people!
When I was getting married in 2005, the guest list was my worst enemy. I HATED trying to gather addresses, keep up with names and spelling of names, and then finally remembering if I'd actually sent them an invitation. If there was a point of breakdown, the guest list was it.
So Lacey, Taylor, Trudy, Hillary, Courtney, Lana, Lindsey M., Lindsey Y., Becca, Melissa, Stephanie, Heather, Rhonda and Blair...check this out!
