Calendar:User tasks

We began first with a brainstorming session that simply listed all of these tasks as people came up with them. Later, we triaged them into the four categories:

• Core: No reasonable calendaring application can ship without
• Necessary: No calendaring application targeting our target users can ship without
• Nice to have: Items that will add substantial value to our product, but which will not block a release of 1.0
• Extension Fodder: Items which we feel do not belong in the shipped application, but which would be good areas to explore in extensions.
