This will become more relevant as we build out team-specific calendars. Until August, pretty much all of our communication will be for everyone. After teams are established, all will use the calendar feature and you'll be able to filter based on the tags for your specific team.
The calendar displays all of the information based on "tags". Each team has a tag, each division has a tag and each key area of the website has a tag.
Once you get the calendar customized, you may use the buttons on the bottom to subscribe to the feeds (i.e. bring them into your desktop calendar, or smartphone)!
