Other guests can be invited to an event, and permission for those guests to invite others may be granted as well.
Event creation can be done through a simple process of clicking a desired time within a date, entering some details, and saving it. If that’s too complicated, Google also provides the Quick Add feature.
Quick Add takes a natural language approach similar to that used by other calendar services like 30 Boxes. Clicking Quick Add brings up a single box, where the user can enter, “Doctor’s appointment 9am Friday,” click the + sign on the box, and see the event tossed into the correct date and timeframe on the calendar.
Once entered, events can be edited or deleted as needed. Events can be duplicated, or set to repeat for events like tedious weekly meetings with an overpaid, backstabbing network manager as a purely random example.
The Google Calendar works well in Firefox 1.5 and Internet Explorer 6. Its Ajax interface operates quickly, and the controls seem intuitive enough for new users to quickly grasp.
