The image below shows the objects that are contained in your website's root container. While sites vary slightly by grade level (elementary, middle, high), the information below should give you an idea of what is what. Remember, many pages in your site (the items in the RIGHT column) are not meant to be edited at all - and should be left alone! They are merely there to act as web pages that contain some of the objects that have directory items, the calendar, etc.
