The calendar of events is one of the most used modules in the entire enterprise of online services. It's managed from the central dashboard and posts immediately to your website automatically. It is setup so the public can click a button on your website to "Submit Event" that then routes to the calendar administrators email for their approval. Once approved it appears on the calendar showing through your website. Viewers can toggle the calendar between calendar and events list view.
One great feature we hear about a lot is the ability to invite members to the event so they can simply click a button to let you know if they plan to attend or not. This is perfect for the meeting host to know how many people are planning to show up.
