I was a groomsman in a wedding last week. It was my first uber-geeky event of the sort.
I was rather amazed how long the wedding lasted and how we didn't get griefed [too much].
The couple met through WoW and have .. grouped together for over three years. The IRL side is lagging behind the in-game side because one is in Australia and one is in Virginia. However this appears to be changing this summer. They are both quite sweet folks.
