Views
The Admin has the ability to view the data of the current page in up to 6 views. At the top of the page you will see the view options (above). The current view is highlighted. Switching between the views allows you to select the view that is most convenient for you.
Adding
Use the "New" button at the top of the page to add new data. Fill out the form that pops up and click the "Save" button to save.
Editing
Use the "Edit" button to make changes to data. In some cases you will need to unhide the button before you can click it. If you're currently in Table view you may need to scroll horizontally before you can see the button. In Calendar view click on the "+" icon to unhide the Edit button.
