Why can't I add events to an area calendar on a homepage?

Being able to add events to an area calendar on a homepage requires the Area Calendar Managers Security Role to be granted.Once this has been granted you will notice a '+' symbol on the area calendar of the homepage that will allow you to add events as well as edit or delete events straight from the homepage. It is important to note that if someone is granted this security role, they will automatically get the rights to view content in that area.
