Cool new calendar site out there called Trumba. It lets you set up a calendar for sharing. Normally, not a big deal. What makes it cool is the abliity to automatically sync it up with your desktop outlook calendar and merge the two together. I set up and account for both Cathie and I so that she can access my calendar and I can see hers/our family calendar overlaid as I schedule stuff at work. It also lets her schedule things onto my calendar at work, which I live and die by.

Update: The outlook calendar sync is temporarily down while they fix some bugs. That's why the site is in beta.
