Pinning: Responsibility and Notifications in One System

Using pins you can mark who is responsible for events, tasks or messages:

The event/task drawer is available everywhere under the project tab. This allows you to complete/add/edit your events/tasks regardless of where you are in the application.

You also can choose how to be notified. On the dashboard, you can select to subscribe to e-mail alerts, RSS^ or iCal*. Use whatever makes you comfortable.

^RSS is a messaging format understood by Google Reader, Newsfire, Outlook and others. (RSS in Plain English)

*iCal (or iCalendar) is a calendar format understood by Outlook, Google Calendar, Thunderbird, Apple iCal and others. (Wikipedia)
